What is an example of polymorphism in Java?
Note: The print() method is also an example of polymorphism. It is used to print values of different types like char , int , string , etc. We can achieve polymorphism in Java using the following ways: Method Overriding.What is polymorphism in code example?
Polymorphism occurs when one class is created that extends another one. For instance, let's consider a class Animal and let Cat be a subclass of Animal . So, any cat IS an animal. Here, a Cat satisfies the IS-A relationship for its own type, Cat as well as its super class Animal , and is therefore polymorphic.How to implement polymorphism in Java code?
Polymorphism in Java can be achieved in two ways i.e., method overloading and method overriding. Polymorphism in Java is mainly divided into two types. Compile-time polymorphism can be achieved by method overloading, and Runtime polymorphism can be achieved by method overriding.Any Java object that can pass more than one IS-A test is polymorphic in Java. Therefore, all the Java objects are polymorphic as it has passed the IS-A test for their own type and for the class Object.
