Compiling and Running a Program
When we compile a Java program, the Java compiler converts it into bytecode. This bytecode is a platform-
independent code which can run on any machine without making a single change. A Java compiler is a
program that translates the source code written by us into machine-readable code.
To compile and run a program, follow the given steps:
1 Click on the Compile
button.
If your program is successfully compiled, a message Class compiled – no syntax errors will appear at
the bottom of the code editor window.
Right-click on the HelloWorld 2
class icon.

If you want to make any changes to a program, then double-click on the class icon and make the
required changes. After making the required changes, you need to compile the program again.
