Step 0: Install JDKTo use Eclipse for Java programming, you need to first install Java Development Kit (JDK). For beginners, choose . 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. For Macs. Read . But check the JDK version, you should be using JDK 1. Click . Enter the following codes. Hello . It is because Eclipse performs the so- called incremental compilation, i. Java statement is compiled as and when it is entered. To run the program, right- click anywhere on the source file . If you have more than one files with main() method in one project, you need to right- click the source and choose . 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). 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(). Step 2: Start Debugger. Right click anywhere on the source code (or from the . The program begins execution but suspends its operation at the breakpoint, i. 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 . At each of the step, examine the value of the variables (in the . 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 . You could set a breakpoint at the statement immediately outside the loop (e. Line 1. 1 of the above program), and issue . Always terminate your current debugging session using . Explore the features provided by the debuggers. Other Debugger's Features. Modify the Value of a Variable: You can modify the value of a variable by entering a new value in the . This is handy for temporarily modifying the behavior of a program, without changing the source code. Step- Into and Step- Return: To debug a method, you need to use . This feature is particularly useful for writing source code in full panel. Shorthand Templates (sysout, for..): You can type . Check your system's shortcut key setting in . 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 . That is, Eclipse will offer you the choices, while you are typing. Source Formatting (ctrl- shift- f): Right- click on the source. You could click on the . Select and right- click on the entity to be renamed . Eclipse can rename all the occurrences of the entity. Line Numbers: To show the line numbers, choose . 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 . This sets the default character set used for file encoding, similar to VM's command- line option - Dfile. UTF- 8. Commonly used charsets for Unicode are UTF- 8, UTF- 1. BOM), UTF- 1. 6BE, UTF- 1. LE.

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 . 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 . To create a test case: Right- click on the project . The results are displayed in a special . These packages typically provide a . The native library directories must be included in JRE's property . 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 is needed only if you are interested to debug into the JOGL source codes. For program development, I recommend that you add the JDK (instead of JRE). File I/O in Eclipse. Suppose that your want to write a Java program, which inputs from a text file called . This is a little tricky under Eclipse due to: When you create a text file in Windows' Notepad and saved it as . This is one good reason not to use Notepad for programming at all.

Enter a SQL statement (e. SELECT * FROM tablename) . In Connection profile, set the type and connection name. Right- click on a statement . Right- right on the table . Hence, you need to manually configure the URL for the servlet in the Web Application Deployment Descriptor . The war file will be automatically extracted and deployed. The web application name is the war- filename. You could use Win. Zip (or Win. RAR) to view the content of the war file, as war- file is in ZIP format. Writing a Hello- world JSF Page.
