Packages with inheritance

In this blog, we will see how to customize our inheritance example in different packages.

 

In this example, we will see three different packages pack1, package1 and package2.

Package1 with A class

Package2 with B Class

Pack1 with example2 Class

 

package package1;

public class A

{

            public void methodA()

            {

                        System.out.println(“Welcome in A Class”);

            }

}

 

package package2;

public class B extends package1.A

{

            public void methodB()

            {

                        System.out.println(“Welcome in B Class”);

            }

}

 

package pack1; //            set path of package

class example2

{

                public static void main(String args[])

                {

                                package2.B obj = new package2.B();      

                                obj.methodA();

                                obj.methodB();               

                }

}
