Java Sub Packages

It is also possible to create sub packages for the main package.

           

 Syntax:            package pack1.pack2;

where pack1 is the main package and pack2 is the sub package.

Example:

package pack1;

public class x

{

            public void show()

            {

            System.out.println("Super");

            }

}

package pack1.pack2;

public class y

{

            public void display()

            {

            System.out.println("Sub");

            }

}

import pack1.x;

import pack1.pack2.y;

class che

{

            public static void main(String[] args)

            {

                        x obj=new x();

                        obj.show();

                        y obj1=new y();

                        obj1.display();

            }

}
