Is method overridding is polymorphism

Answer 1

Yes. Method Overriding is a form of Polymorphism.

Overridden Methods

Any time you have a class that inherits a method from a superclass, you have the opportunity to override the method (unless, as you learned in the earlier chapters, the method is marked final). The key benefit of overriding is the ability to define behavior that's specific to a particular subclass type. The following example demonstrates a Porsche subclass of Car overriding the Car version of the drive() method:

public class Car {

public void drive() {

System.out.println("Generic Car Driving Generically");

}

}

class Porsche extends Car {

public void drive() {

System.out.println("Porsche driving Full Throttle");

}

}
