How to Install Eclipse IDE 2019-12 for Java Developers
How to Install Eclipse on Windows
Step 0: Install JDK
To use Eclipse for Java programming, you need to first install Java Development Kit (JDK). Read 'How to Install JDK for Windows'.
Step 1: Download
Download Eclipse from https://www.eclipse.org/downloads. Under 'Get Eclipse IDE 2019-12' ⇒ Click 'Download Packages'. For beginners, choose the 'Eclipse IDE for Java Developers' and 'Windows 64-bit' (e.g., 'eclipse-java-2019-12-R-win32-x86_64.zip
' - about 201MB) ⇒ Download.
How To Download Eclipse C For Mac Download
Step 2: Unzip
To install Eclipse, simply unzip the downloaded file into a directory of your choice (e.g., 'c:myProject
').
I prefer the zip version, because there is no need to run any installer. Moreover, you can simply delete the entire Eclipse directory when it is no longer needed (without running any un-installer). You are free to move or rename the directory. You can install (unzip) multiple copies of Eclipse in the same machine.
How to Install Eclipse on macOS
To use Eclipse for Java programming, you need to first install JDK. Read 'How to install JDK for macOS'.
To install Eclipse:
- Goto http://www.eclipse.org/downloads/. Under 'Get Eclipse IDE 2019-12' ⇒ Click 'Download Packages'. For beginners, select 'Eclipse IDE for Java Developers' and 'Mac Cocoa 64-bit'. You will receive a DMG file (e.g., '
eclipse-java-2019-12-R-macosx-cocoa-x86_64.dmg
'). - Double-click the downloaded Disk Image (DMG) file. Follow the screen instructions to install Eclipse. Eclipse will be installed under '
/Applications/eclipse
'. (To confirm!)
How to Install Eclipse on Ubuntu Linux
Eclipse comes with many flavors (See 'Eclipse Packages' @ https://www.eclipse.org/downloads/compare.php):
- To use Eclipse for Java programming, choose 'Eclipse IDE for Java Developers' (JavaSE) or 'Eclipse IDE for Java EE Developers' (JavaEE). You need to first install JDK. Read 'How to install JDK on Ubuntu'.
- To use Eclipse for PHP programming, choose 'Eclipse IDE for PHP Developers'.
- To use Eclipse for C/C++ programming, choose 'Eclipse IDE for C/C++ Developers'.
Nonetheless, you can install any package, and then add more features when needed.
To install Eclipse (e.g, for Java Programming):
- Download Eclipse from http://www.eclipse.org/downloads/. Under 'Get Eclipse IDE 2019-12' ⇒ Click 'Download Packages'. Choose 'Eclipse IDE for Java Developers' for Java SE program development; or 'Eclipse IDE for Java EE Developers' for developing webapps ⇒ Linux 64-bit. You will receive a tarball (e.g., '
eclipse-java-2019-12-R-linux-gtk-x86_64.tar.gz
') in the '~/Downloads
' folder. - We shall install Eclipse under
/usr/local
.
To run Eclipse, open the '/usr/local/eclipse
' folder and click on the 'Eclipse' icon; or start a 'Terminal', enter 'eclipse'.
Lock Eclipse on Launcher
Simply start Eclipse. Right-click the Eclipse icon ⇒ Lock to Launcher.
(For older version - If the above don't work) Create a /usr/share/applications/eclipse.desktop
file with the following contents:
Start Eclipse, right-click on the Eclipse icon on launcher ⇒ lock to launcher.
Writing your First Java Program in Eclipse
Step 0: Launch Eclipse
- Launch Eclipse by running '
eclipse.exe
' from the Eclipse installed directory. - Choose an appropriate directory for your workspace, i.e., where you would like to save your files (e.g.,
c:myProjecteclipse
for Windows) ⇒ Launch. - If the 'Welcome' screen shows up, close it by clicking the 'close' button next to the 'Welcome' title.
How To Download Eclipse C For Mac Ac Os X
Step 1: Create a new Java Project
For each Java application, you need to create a project to keep all the source files, classes and relevant resources.To create a new Java project:
- Choose 'File' menu ⇒ 'New' ⇒ 'Java project' (or 'File' ⇒ 'New' ⇒ 'Project' ⇒ 'Java project').
- The 'New Java Project' dialog pops up.
- In 'Project name', enter '
FirstProject
'. - Check 'Use default location'.
- In 'JRE', select 'Use default JRE (currently 'JDK11.0.x')'. But make sure that your JDK is 1.8 and above.
- In 'Project Layout', check 'Use project folder as root for sources and class files'.
- In 'Project name', enter '
- In 'Create module-info.java' dialog, Click 'Don't Create'. (Note: For easier version of Eclipse, you need to use the 'Next' Button in the previous step, and uncheck 'Create module-info.java file').
Step 2: Write a Hello-world Java Program
- In the 'Package Explorer' (left pane) ⇒ Right-click on '
FirstProject
' (or use the 'File' menu) ⇒ New ⇒ Class. - The 'New Java Class' dialog pops up.
- In 'Source folder', keep the 'FirstProject'.
- In 'Package', delete the content if it is not empty.
- In 'Name', enter '
Hello
'. - Check '
public static void main(String[] args)
'. - Don't change the rest.
- The source file '
Hello.java
' opens on the editor panel (the center pane). Enter the following codes:
Step 3: Compile & Execute the Java Program
- There is no need to compile the Java source file in Eclipse explicitly. It is because Eclipse performs the so-called incremental compilation, i.e., the Java statement is compiled as and when it is entered.
- To run the program, right-click anywhere on the source file '
Hello.java
' (or choose 'Run' menu) ⇒ Run As ⇒ Java Application. - The output 'Hello, world!' appears on the Console panel (the bottom pane).
NOTES:
- You should create a NEW Java project for EACH of your Java application.
- Nonetheless, Eclipse allows you to keep more than one programs in a project, which is handy for writing toy programs (such as your tutorial exercises). To run a particular program, open and right-click on the source file ⇒ Run As ⇒ Java Application.
- Clicking the 'Run' button (with a 'Play' icon) runs the recently-run program (based on the previous configuration). Try clicking on the 'down-arrow' besides the 'Run' button.
Correcting Syntax Errors
Eclipse performs incremented compilation, as and when a source 'line' is entered. It marked a source line having syntax error with a RED CROSS. Place your cursor at the RED CROSS to view the error message.
You CANNOT RUN the program if there is any syntax error (marked by a RED CROSS before the filename). Correct all the syntax errors; and RUN the program.
HINTS: In some cases, Eclipse shows a ORANGE LIGHT-BULB (for HINTS) next to the ERROR RED-CROSS (Line 5 in the above diagram). You can click on the LIGHT-BULB to get a list of HINTS to resolve this particular error, which may or may not work!
SYNTAX WARNING: marked by a orange triangular exclaimation sign. Unlike errors, warnings may or may not cause problems. Try to fix these warnings as well. But you can RUN your program with warnings.
Read the Eclipse Documentation
At a minimum, you SHOULD browse through Eclipse's 'Workbench User Guide' and 'Java Development User Guide' - accessible via the Eclipse's 'Welcome' page or 'Help' menu. This will save you many agonizing hours trying to figure out how to do somethings later.
Debugging Programs in Eclipse
Able to use a graphics debugger to debug program is crucial in programming. It could save you countless hours guessing on what went wrong.
Step 0: Write a Java Program
The following program computes and prints the factorial of n
(=1*2*3*..*n
). The program, however, has a logical error and produce a wrong answer for n
=20
('The Factorial of 20 is -2102132736
' - a negative number?!).
Let's use the graphic debugger to debug the program.
Step 1: Set an Initial Breakpoint
A breakpoint suspends program execution for you to examine the internal states (e.g., value of variables) of the program. Before starting the debugger, you need to set at least one breakpoint to suspend the execution inside the program. Set a breakpoint at main()
method by double-clicking on the left-margin of the line containing main()
. A blue circle appears in the left-margin indicating a breakpoint is set at that line.
Step 2: Start Debugger
Right click anywhere on the source code (or from the 'Run' menu) ⇒ 'Debug As' ⇒ 'Java Application' ⇒ choose 'Yes' to switch into 'Debug' perspective (A perspective is a particular arrangement of panels to suits a certain development task such as editing or debugging). The program begins execution but suspends its operation at the breakpoint, i.e., the main()
method.
As illustrated in the following diagram, the highlighted line (also pointed to by a blue arrow) indicates the statement to be executed in the next step.
Step 3: Step-Over and Watch the Variables and Outputs
Click the 'Step Over' button (or select 'Step Over' from 'Run' menu) to single-step thru your program. At each of the step, examine the value of the variables (in the 'Variable' panel) and the outputs produced by your program (in the 'Console' Panel), if any. You can also place your cursor at any variable to inspect the content of the variable.
Single-stepping thru the program and watching the values of internal variables and the outputs produced is the ultimate mean in debugging programs - because it is exactly how the computer runs your program!
Step 4: Breakpoint, Run-To-Line, Resume and Terminate
As mentioned, a breakpoint suspends program execution and let you examine the internal states of the program. To set a breakpoint on a particular statement, double-click the left-margin of that line (or select 'Toggle Breakpoint' from 'Run' menu).
'Resume' continues the program execution, up to the next breakpoint, or till the end of the program.
'Single-step' thru a loop with a large count is time-consuming. You could set a breakpoint at the statement immediately outside the loop (e.g., Line 11 of the above program), and issue 'Resume' to complete the loop.
Alternatively, you can place the cursor on a particular statement, and issue 'Run-To-Line' from the 'Run' menu to continue execution up to the line.
'Terminate' ends the debugging session. Always terminate your current debugging session using 'Terminate' or 'Resume' till the end of the program.
Step 5: Switching Back to Java perspective
Click the 'Java' perspective icon on the upper-right corner to switch back to the 'Java' perspective for further programming (or 'Window' menu ⇒ Open Perspective ⇒ Java).
Important: I can's stress more that mastering the use of debugger is crucial in programming. Explore the features provided by the debuggers.
Other Debugger's Features
Step-Into and Step-Return: To debug a method, you need to use 'Step-Into' to step into the first statement of the method. ('Step-Over' runs the function in a single step without stepping through the statements within the function.) You could use 'Step-Return' to return back to the caller, anywhere within the method. Alternatively, you could set a breakpoint inside a method.
Modify the Value of a Variable: You can modify the value of a variable by entering a new value in the 'Variable' panel. This is handy for temporarily modifying the behavior of a program, without changing the source code.
Tips & Tricks
General Usages (for all Programming Tasks)
These are the features that I find to be most useful in Eclipse:
- Maximizing Window (Double-Clicking): You can double-click on the 'header' of any panel to maximize that particular panel, and double-click again to restore it back. This feature is particularly useful for writing source code in full panel.
- Shorthand Templates (sysout, for,..): You can type '
sysout
' followed by a ctrl+space (or alt-/) as a shorthand for typing 'System.out.println()
'.
The default shortcut key (ctrl-space or alt-/) depends on the system. Check your system's shortcut key setting in 'Edit' ⇒ 'Content Assist' ⇒ 'Default'. Take note that many of you use ctrl+space to switch between input languages. You need to reconfigure either your language switching hot-key or Eclipse.
Similarly, you can type 'for' followed by ctrl-space (or alt-/) to get a for-loop.
You can create your own shorthand in 'Window' menu ⇒ 'Preferences' ⇒ 'Java' ⇒ 'Editor' ⇒ 'Templates'. (Alternatively, in 'Window' ⇒ 'Preferences' ⇒ type 'template' as filter text and choose 'Java' ⇒ 'Editor' ⇒ 'Templates'.)
You can change your key settings in 'Window' menu ⇒ 'Preferences' ⇒ 'General' ⇒ 'Key' ⇒ choose 'Command', 'Content Assist'. (Alternatively, in 'Window' ⇒ 'Preferences' ⇒ type 'key' as filter text and choose 'General' ⇒ 'Key'.) - Intelli-Sense (ctrl-space): You can use ctrl-space to activate the 'intelli-sense' (or content assist). That is, Eclipse will offer you the choices, while you are typing.
- Source Formatting (ctrl-shift-f): Right-click on the source. Choose 'Source' ⇒ 'Format' to let Eclipse to layout your source codes with the proper indentation.
- Source Toggle Comment (ctrl-/): To comment/uncomment a block of codes, choose 'Source' ⇒ 'Toggle Comment'.
- Hints for Correcting Syntax Error: If there is a syntax error on a statement, a red mark will show up on the left-margin on that statement. You could click on the 'light bulb' to display the error message, and also select from the available hints for correcting that syntax error.
- Refactor (or Rename) (alt-shift-r): You can rename a variable, method, class, package or even the project easily in Eclipse. Select and right-click on the entity to be renamed ⇒ 'Refactor' ⇒ 'Rename'. Eclipse can rename all the occurrences of the entity.
- Line Numbers: To show the line numbers, choose 'Window' menu ⇒ 'Preferences' ⇒ 'General' ⇒ 'Editors' ⇒ 'Text Editors' ⇒ Check the 'Show Line Numbers' Box. You can also configure many editor options, such as the number of spaces for tab. Alternatively, you can right-click on the left-margin, and check 'Show Line Numbers'.
- Error Message Hyperlink: Click on an error message will hyperlink to the corresponding source statement.
- Changing Font Type and Size: From 'Window' menu ⇒ 'Preferences' ⇒ 'General' ⇒ 'Appearance' ⇒ 'Colors and Fonts' ⇒ expand 'Java' ⇒ 'Java Editor Text Font' ⇒ 'Edit'. (Alternatively, in 'Window' ⇒ 'Preferences' ⇒ type 'font' as filter text and choose the appropriate entry.)
- Unicode Support: To enable Unicode support, select 'Window' menu ⇒ Preferences ⇒ General ⇒ Workspace ⇒ Text file encoding ⇒ UTF-8. This sets the default character set used for file encoding, similar to VM's command-line option
-Dfile.encoding=UTF-8
. Commonly used charsets for Unicode are UTF-8, UTF-16 (with BOM), UTF-16BE, UTF-16LE. Other charsets are US-ASCII, ISO-8859-1. - Mouse Hover-over: In debug mode, you could configure to show the variable's value when the mouse hovers over the variable. Select 'Window' menu ⇒ 'Preferences' ⇒ 'Java' ⇒ 'Editor' ⇒ 'Hover'.
- Comparing Two Files: In 'Package Explorer', select two files (hold the control key) ⇒ Right-click ⇒ Compare with.
- Useful Eclipse Shortcut Keys:
- F3: Goto the declaration of the highlighted variable/method.
- Ctrl-Shift-G: Search for ALL references of the highlighted variable/method in workspace.
- Ctrl-G: Search for the Declaration of a variable/method in workspace.
Don't use Find (Ctrl-F), but use the above context-sensitive search. - Ctrl-Shift-F: Format the source code.
- Ctrl-Shift-O: Organize imports.
- Alt-Shift-R: Rename. (Don't use Find/Replace.)
- Ctrl-Space: auto-complete.
- Package Explorer vs. Navigator: We usually use 'Package Explorer' in programming, but it will not show you all the folders and files under the project. On the other hand, 'Navigator' is a file manager that shows the exact file structure of the project (similar to Windows Explorer). You can enable the Navigator by 'Window' ⇒ Show view ⇒ Navigator.
- Spell Check: To enable spell check, select Window ⇒ Preferences ⇒ type 'spell' in the filter ⇒ General ⇒ Editors ⇒ Text Editors ⇒ Spelling ⇒ Check 'Enable spell checking'. Also provide a 'User defined dictionary' (with an initially empty text file).
To correct mis-spell words, right-click and press ctrl-1 (or Edit menu ⇒ Quick Fix). - Eclipse's Log File: Goto Help ⇒ about Eclipse ⇒ Installation details ⇒ Configuration ⇒ View Error Log.
- Viewing two files in split screen: Simply click and hold on the title of one file and drag it to the lower side of the screen. [To view the same file on split screen, create a new editor window by selecting Window ⇒ New Editor; and drag one window to the lower side of the screen.]
- Block Select (Column Select): Push Alt-Shift-A to toggle between block-select mode and normal mode.
- Snippets:
- To view the snippet window: choose 'Window' ⇒ Show View ⇒ Snippets.
- To create a new snippet category: Right-click ⇒ Customize ⇒ New.
- To create a new snippet item: Copy the desired text ⇒ Select the snippet category ⇒ paste as snippet.
- To insert a snippet: place the cursor on the desired location at the editor panel ⇒ click the snippet item.
- Word Wrap (Line Wrap): Word-wrap (or line-wrap) is essential for editing long HTML documents without the horizontal scroll bar. However, the Eclipse's HTML Editor and Text Editor do not support word-wrap.
You could install a plug-in called 'Word Wrap' from http://ahtik.com/eclipse-update/.
Choose 'Help' ⇒ Install New Software ⇒ in 'Work with' Enter 'http://ahtik.com/eclipse-update/'.
To activate word wrap, right-click on the editor panel ⇒ select 'Word Wrap'. - Creating 'link folder' in project: You do not have to place all the folders under the project base directory, instead, you can use so-called 'link folders' to link to folder outside the project base directory.
To create a link folder in a project, right-click on the project ⇒ File ⇒ New ⇒ Folder ⇒ Advanced ⇒ Check Link to alternate Location (Linked Folder). - Running Eclipse in 'clean' mode: You can run eclipse in so-called '
clean
' mode, which wipes all the cached data and re-initialize the cache, by running eclipse from command-line with '-clean' argument (i.e., 'eclipse -clean
'). It is useful if something is not working proper, especially if you install a new copy of Eclipse. - Show the Right Margin: Window ⇒ Preferences ⇒ General ⇒ Editors ⇒ Text Editors ⇒ Show Print Margin and set the column number.
- Let me know if you have more tips to be included here.
Update Eclipse and Install new Software
- Install New Software: Select 'Help' menu ⇒ Install New Software ⇒ In 'Work With', pull down the select menu and choose a software site.
- Update: Select 'Help' menu ⇒ Check for Updates ⇒.
For Java Application Development Only
- Small Toy Java Programs: You can keep many small programs (with
main()
) in one Java project instead of create a new project for each toy program. To run the desired program, right-click on the source file ⇒ 'Run as' ⇒ 'Java Application'. - Scanner/printf() and JDK 1.5: If you encounter syntax error in using
printf()
orScanner
(which are available from JDK 1.5), you need to check your compiler settings. Select 'Window' menu ⇒ Preferences ⇒ open the 'Java' node ⇒ select 'Compiler' ⇒ in 'Compiler compliance level' ⇒ select the latest release, which should be '1.5' or above. - Command-Line Arguments: To provide command-line arguments to your Java program in Eclipse, right-click on the source file ⇒ 'Run Configurations' ⇒ Under the 'Main' panel, check that 'Project' name and 'Main Class' are appropriate ⇒ Select the 'Argument' tab ⇒ type your command-line arguments inside the 'Program Arguments' box ⇒ 'Run'.
- Resolving Import (Ctrl-Shift-o): To ask Eclipse to insert the
import
statements for classes. Useful when you copy a large chunk of codes without the corresponding import statements. - Including Another Project: To include another project in the same work space, right-click on the project ⇒ Build Path ⇒ Configure Build Path.. ⇒ Select 'Projects' tab ⇒ 'Add..' to select project in the existing work space ⇒ OK.
- Exporting a Project to a JAR file: Right-click on the project ⇒ Export.. ⇒ Java, JAR File ⇒ Next ⇒ Select the files to be exported ⇒ Next ⇒ Next ⇒ In 'JAR Manifest Specification' dialog, enter the main class (if you wish to run the JAR file directly) ⇒ Finish.
- Unit Testing: If you keep your test in another project, you need to include the project under test in your Build Path (see above).
To create a test case: Right-click on the project ⇒ New ⇒ JUnit Test Case ⇒ the 'New JUnit Test Case' dialog appears. Select 'New JUnit 4 Test'. In 'Name', enter your class name. In 'Class under test', browse and select the class to be tested.
To run the test: Right-click ⇒ 'Run As' ⇒ 'JUnit Test'. The results are displayed in a special 'JUnit console'. - Adding External JAR files & Native Libraries ('.dll', '.lib', '.a', '.so'): Many external Java packages (such as JOGL, Java3D, JAMA, etc) are available to extend the functions of JDK. These packages typically provide a '
lib
' directory containing JAR files ('.jar
') (Java Archive - a single-file package of Java classes) and native libraries ('.dll
', '.lib
' for windows, '.a
', '.so
' for Linux and macOS).
To include these external packages into an Eclipse's project, right-click on the project ⇒ Build Path ⇒ Add External Archives ⇒ Navigate to select the JAR files ('.jar
') to be included.
In 'Package Explorer', right-click on the JAR file added ⇒ Properties:- To include native libraries ('
.dll
', '.lib
', '.a
', '.so
'), select 'Native Library' ⇒ 'Location Path' ⇒ 'External Folder'. - To include the javadoc, select 'JavaDoc Location' ⇒ 'JavaDoc URL' ⇒ You can specify a local file or a remote link.
- To include source file (for debugging), select 'Java Source Attachment'.
Notes: The JAR files must be included in theCLASSPATH
. The native library directories must be included in JRE's property 'java.library.path
', which normally but not necessarily includes all the paths from thePATH
environment variable. Read 'External JAR files and Native Libraries'. - To include native libraries ('
- Creating a User Library: You can also create a Eclipse's user library to include a set of JAR files and native libraries, that can then be added into subsequent Eclipse projects.
For example, I created a user library for 'JOGL' as follows:- From 'Window' menu ⇒ Preferences ⇒ Java ⇒ Build Path ⇒ User Libraries ⇒ New ⇒ In 'User library name', enter '
jogl
'. The 'User Library' dialog appears. - In 'User Library' dialog ⇒ Select '
jogl
' ⇒ Add JAR.. ⇒ Navigate to<JOGL_HOME>/lib
, and select 'gluegen-rt.jar
' and 'jogl.jar
'. - Expand the '
jogl.jar
' node ⇒ Select 'Native library location: (none)' ⇒ Edit.. ⇒ External Folder.. ⇒ select<JOGL_HOME>/lib
. - Expand the '
jogl.jar
' node ⇒ Select 'Javadoc location: (none)'
⇒ Edit.. ⇒ Javadoc in archive ⇒ In 'Archive Path', 'Browse' and select the downloaded JOGL API documentation zip-file ⇒ In 'Path within archive', 'Browse' and expand the zip-file to select the top-level path (if any) ⇒ Validate. Alternatively, you can provide the path to the un-zipped javadocs. This is needed for Eclipse to display javadoc information about classes, fields, and methods. - You may provide the source files by editing 'Source attachment: (none)'. Source is needed only if you are interested to debug into the JOGL source codes.
jogl
'. - From 'Window' menu ⇒ Preferences ⇒ Java ⇒ Build Path ⇒ User Libraries ⇒ New ⇒ In 'User library name', enter '
- Running an External Program: Suppose that you want to run a Perl script on the selected file, you can configure an external tool as follows:
- From 'Run' menu ⇒ External Tools ⇒ External Tools Configuration.. ⇒ The 'External Tools Configuration' dialog appears.
- In 'Name', enter your tool name.
- Choose the 'Main' tab ⇒ In 'Location', 'Browse File System..' to choose the perl interpreter 'perl' ⇒ In 'Arguments', enter '
path/scriptname.pl ${resource_loc}
', where${resource_loc}
is an Eclipse variable that denotes the currently selected resource with absolute path. - Choose the 'Common' tab ⇒ In 'Standard Input and Output', uncheck 'Allocate Console', check 'File' and provide an output file (e.g.,
d:temp${resource_name}.txt
). - (If you use the CYGWIN perl interpreter, need to set environment variable CYGWIN=nodosfilewarning to disable warning message.)
- Viewing Hex Code of Primitive Variables in Debug mode: In debug perspective, 'Variable' panel ⇒ Select the 'menu' (inverted triangle) ⇒ Java ⇒ Java Preferences.. ⇒ Primitive Display Options ⇒ Check 'Display hexadecimal values (byte, short, char, int, long)'.
- Adding a New Version of JDK/JRE: First, you can check the installed JDK/JRE via 'Window' menu ⇒ 'Preferences' ⇒ Expand 'Java' node ⇒ 'Installed JREs'. Check the 'Location' current JRE installed to make sure that it is the intended one. You can use the 'Add' button to add a new version of JRE. For program development, I recommend that you add the JDK (instead of JRE). [The 'Location' decides the extension directory used for including additional JAR files, e.g.,
$JAVA_HOMEjrelibext
.]
For Web Developers
- HTML Editor: Use the 'Web Page Editor' (available in Eclipse Java EE), which provides the design view (WYSISYG).
To use the 'Web Page Editor', right-click on the HTML file, open as 'Web Page Editor'.
To make the 'Web Page Editor' as default for HTML file, goto Window ⇒ Preferenes ⇒ General ⇒ Editor ⇒ File Associations ⇒ .htm and .html ⇒ Select 'Web page editor' ⇒ default.
File I/O in Eclipse
Suppose that your want to write a Java program, which inputs from a text file called 'xxxx.in
' and outputs to a text file called 'xxxx.out
'. This is a little tricky under Eclipse due to:
- When you create a text file in Windows' Notepad and saved it as '
xxxx.in
', Notepad will append the '.txt
' to your file and it becomes 'xxxx.in.txt
'. Worse still, the Windows' Explorer, by default, will not show the '.txt
' extension. (The first thing I always do to an alien computer is to change this setting. From 'Tools' menu ⇒ Folder Options.. ⇒ View ⇒ Uncheck 'Hide extensions for known file types'.) You need to put a pair of double quotes aroundxxxx.in
to override the default '.txt
' extension. This is one good reason not to use Notepad for programming at all. You should use Eclipse to create the text file instead. - Which directory to keep the input file '
xxxx.in
' in Eclipse?- If you did not separate the sources and class files into two separate directories, then the answer is straight forward, because there is only one directory to place your input file.
- If you choose to keep your sources and class files in two separate directories, eclipse will create two sub-directories 'src' and 'bin' under the base directory. BUT you need to put your input file '
xxxx.in
' in the base directory of your project, instead of the 'src' or 'bin'.
- Put the sources, class files, and the input/output files in the same directory. (When you create a new project, select 'Use project folder as root for sources and class files' in 'Project Layout'.) (But put your sources and class files in separate directories for big project.)
- You can create you input file from eclipse directly via 'File' menu ⇒ 'New' ⇒ 'File'.
- Remember to add a newline to the end of your input file.
- You may need to right-click the project and select 'Refresh' to see the output file '
xxxx.out
' created in the package explorer. - To open the '
xxxx.in
' and 'xxxx.out
': right-click ⇒ Open With ⇒ Text Editor.
This is a sample JDK 1.5 program for file input/output:
Create the input text file called 'FileIOTest.in
