Runtime polymorphism or dynamic method dispatch is a process in which a call to an overridden method is resolved at runtime rather than at compile-time. In this process, an overridden method is called through the reference variable of a superclass. The determination of the method to be called is based on the object being referred to by the reference variable.
class Bike{
void run(){System.out.println("running");}
}
class Splendor extends Bike{
void run(){System.out.println("I am running safely with 60km");}
public static void main(String args[]){
Bike b = new Splendor();//upcasting
b.run();
}
}
Test it Now
Output:
I am running safely with 60km.
