What is a package?

• A package is a namespace concept which organizes a set of related interfaces and classes.
• It can be thought of as different folders on your system.

Implementing Package

package com.pratikkataria.java;

public class Main {
	public static void main( String[] args) {
		System.out.println(args[0]);
	}
}

• This Main.java file needs to be kept inside folders:
  • com -> pratikkataria -> java -> Main.java
• So the command prompt needs to be started in the location where the com folder is:
  • K:\>
• CONSOLE:
  • K:\>javac com\pratikkataria\java\Main.java
  • K:\>java com.pratikkataria.java.Main MyArg
• OUTPUT:
  • MyArg
