INHERITANCE IN JAVA AND INHERITANCE WITH ONE EXAMPLE

Inheritance:

It is a concept provided in java which is used for extending the parent class stuff to the child class.

Note: one class can’t extend more than one classes at a time in java.

          one class can implement one or more interfaces at a time.

Develop a java program to produce the following o/p using inheritance

package pack1;

publicclass father {

          publicvoid earn()

          {

                   System.out.println("logic for father earning");

          }

          publicvoid drive()

          {

                   System.out.println("logic for father driving");

          }

         

publicclass son extends father {

publicvoid drive() {

         

System.out.println("logic for son drive");

}

publicvoid study() {

System.out.println("logic for son study");

}

}

publicclassgrandsonextends son {

publicvoid play() {

         

System.out.println("logic for grand son play");

}

publicvoid study() {

System.out.println("logic for grand son study");

}

}

          publicstaticvoid main(String[] args) {

         

                   father f1=new father();

                   f1.earn();

                   f1.drive();

                   f1.earn();

                  

          }

}
