[Tutorial] How to Compile a Java program in Eclipse

[Vishal Lad]

Step 1:
When you start eclipse, it asks your for the address of the workspace. Workspace is a folder where eclipse will store all your project files.


Step 2:

To start a new project go to <strong>New->JAVA project</strong>.


Step 3:
Enter the details of your project i.e your project name.


Step 4:

Create a new class. To do this right click on your project name which is "MyProject" in this case and select <strong>New->Class</strong>.



Step 5:

Enter the name of your class. Click finish.



Step 6: Compiling

To compile, just press the RUN button or the DEBUG button to the left of the run button.

Not completely true. You don't need to run or debug an application to compile it.

Nice attempt to get people on board with Eclipse and Java!

In step 5, I would click the "public static void main(String[] args)" checkbox.

You've used "compiling" to be the same as "running," which isn't entirely correct. I don't know if Eclipse allows one to compile Java source code to class files without running the project. It seems not, but maybe I just haven't figured out how, and in spite of its title, this How To doesn't show me.

Yes, it does this. By default is does this automatically every time you save the java source file. You can change this in the Preferences under General | Workspace. If you turn off automatic builds, you can right-click a project and select Build Project.

Good to know. Thanks.
