Write a java script showing static and dynamic polymorphism

speak() is same because according to compiler both methods are called on Mammal reference but the output for both method calls is different because at runtime JVM knows what object a reference is holding and JVM calls the method on the object and this is why Method Overriding is known as Dynamic Polymorphism.26 Ara 2013

Dynamic Polymorphism C# allows you to create abstract classes that are used to provide partial class implementation of an interface . Implementation is completed when a derived class inherits from it. Abstract classes contain abstract methods, which are implemented by the derived class.

Runtime polymorphism is also known as dynamic polymorphism or late binding. In runtime polymorphism, the function call is resolved at run time . In contrast, to compile time or static polymorphism, the compiler deduces the object at run time and then decides which function call to bind to the object.

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. In fact, any object that satisfies more than one IS-A relationship is polymorphic in nature.
