How is polymorphism implemented in Java?

Can you explain how polymorphism is implemented in Java?

Sure! In Java, polymorphism allows methods to do different things based on the object that it is acting upon. It can be achieved through method overriding and method overloading.

What’s the difference between method overriding and method overloading?

Method overriding occurs when a subclass provides a specific implementation of a method that is already defined in its superclass. Method overloading, on the other hand, allows multiple methods in the same class to have the same name but different parameters.

Can you give me an example of polymorphism in Java?

Certainly! For example, if you have a superclass called Animal with a method makeSound(), subclasses like Dog and Cat can override this method to provide their specific sounds. When you call makeSound() on an Animal reference, it will execute the overridden method of the actual object type.

How does polymorphism improve code flexibility?

Polymorphism enhances code flexibility by allowing you to write more generic and reusable code. You can use a single interface or superclass reference to interact with different subclasses, making it easier to extend and maintain your code.
