Polymorphism is the ability of an object to take on many forms. In Java, it is achieved through method overriding and interfaces.

• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• Method overriding is when a subclass provides its own implementation of a method that is already defined in its superclass.

• Interfaces allow for polymorphism by defining a set of methods that a clas...read more
