What is the benefit of polymorphism in Java.

Question text what is the advantage of runtime polymorphism. Java - Interview Questions and Answers on Polymorphism. You can overload a method with different sets of parameters. That means we override that method.

An example is shown below. It allows a class to specify methods that will be common to all of its derivatives while allowing subclasses to define the specific implementation of some or all of those methods. In your sample of third part use this structers then it see Parent interface only and dont know implementation in runtime so.

Polymorphism is One of the principles OOP. Overriding - Overriding the Definition of base class in the derived class. You dont want to write separate methods for each object from different classes that would get tedious.

Run-time polymorphism allows you to write generalised code which can be used by many different subclasses. Answer options only 2 are valid. This transfer of implementation of one method to another method is possible without changing or modifying the codes of the parent class object.

Runtime Polymorphism or Late Binding. Do you think answer is difficult. In Run time polymorphism methods get resolved at Run Time.

Advantages of Dynamic Polymorphism Dynamic Polymorphism allows Java to support overriding of methods which is central for run-time polymorphism. Polymorphism allows you to invoke derived class methods through a base class reference during run-time. Why is it called Runtime Polymorphism.
