Suppose we have a file called, and put this file in a package world. The we specify the keyword package with the name of the package.

package world;

public class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello World");

When compiling HelloWorld class, just go to the world directory and type the command:


Then run as:

C:\world>java world.HelloWorld
