What is polymorphism in Java?
Polymorphism in Java allows methods to do different things based on the object that it is acting upon. It enables one interface to be used for a general class of actions.
Can you give me an example of polymorphism?
Sure! For instance, if you have a superclass called 'Animal' with a method 'sound()', subclasses like 'Dog' and 'Cat' can implement 'sound()' differently. When you call 'sound()' on an 'Animal' reference, it will execute the method of the actual object type.
How does polymorphism improve code flexibility?
Polymorphism improves code flexibility by allowing you to write more generic and reusable code. You can use the same method name for different types, making it easier to extend and maintain.
What are the two types of polymorphism in Java?
The two types of polymorphism in Java are compile-time (or static) polymorphism, which is achieved through method overloading, and runtime (or dynamic) polymorphism, which is achieved through method overriding.
