Compile and Run Java Programs

This section describes how to compile and run Java programs.

When JDK is installed on your machine, it provides two commands for you to compile and run Java programs.

Let's try these commands with a very simple Java program. Use NotePad to enter the following Java program into a file called Hello.java:

class Hello {
   public static void main(String[] a) {
      System.out.println("Hello world!");
   }
}

Then compile this program in a command window with the "javac" command:

herong> javac Hello.java

To execute the program, use the java command:

herong> java Hello

Hello world!

Congratulations, you have successfully entered, compiled and executed your first Java program.
