What is an example of polymorphism in Java?

Method overloading is an example of static polymorphism, while method overriding is an example of dynamic polymorphism. An important example of polymorphism is how a parent class refers to a child class object. For instance, let’s consider a class Animal and let Cat be a subclass of Animal . So, any cat IS animal.

interface I{}
class A{}
class B extends A implements I{}

How does Java implement polymorphism?

Java implements polymorphism in two ways: 1. Static or compile-time polymorphism is done by method overloading (more then one methods sharing the same name but different number/types/order of parameters) 2. Dynamic or runtime polymorphism is done by method overriding (defining a method in the child…

What are the rules to polymorphism in Java?

Below are some of the rules and limitations of runtime polymorphism: Methods of child and parent class must have the same name . Methods of child and parent class must have the same parameter . IS-A relationship is mandatory (inheritance). One cannot override private methods of a parent class. One cannot override Final methods.

What is polymorphism in Java and its types?

When applied to object-oriented programming languages like Java, it describes a language’s ability to process objects of various types and classes through a single, uniform interface. Polymorphism in Java has two types: Compile time polymorphism (static binding) and Runtime polymorphism (dynamic binding).
