Run Time Polymorphism Example Java Program

Run Time Polymorphism Example Program

class ClassA{
    public void disp(){
        System.out.println ("I am inside Class A");
    }
}
class ClassB extends ClassA{
    public void disp(){
        System.out.println ("I am inside Class B");
    }
}
public class RunTimePolymorphismDemo{
   public static void main (String args []) {
       ClassA obj1 = new ClassA();
       ClassA obj2 = new ClassB();
       obj1.disp();
       obj2.disp();
   }
}

Sample Output

Output is:
I am inside Class A
I am inside Class B
