Polymorphism

Polymorphism

1. Compile Time

   • A class can have a more than one method with the same name but different no of arguments or both
     • Method Overloading

2. Runtime

   • In this example, we are creating two classes Bike and Splendar. Splendar class extends Bike class and overrides its run() method. We are calling the run method by the reference variable of Parent class. Since it refers to the subclass object and subclass method overrides the Parent class method, subclass method is invoked at runtime. Since method invocation is determined by the JVM not compiler, it is known as runtime polymorphism.
