Dynamic Method Dispatchĭynamic method dispatch is a mechanism that enables Java to decide at runtime which method implementation to call based on the type of the object. When we create a Dog object and call its makeSound() method, the overridden method in the Dog class is executed instead of the method in the Animal class. In the example above, the Dog class overrides the makeSound() method of the Animal class. MyDog.makeSound() // Output: The dog barks MyAnimal.makeSound() // Output: The animal makes a sound Here's an example that demonstrates method overriding: This allows the subclass to inherit the methods and fields of the superclass and customize them as needed. The new implementation in the subclass must have the same method signature, including the method name, return type, and parameters, as the method in the superclass. Method overriding occurs when a subclass provides a new implementation for a method that is already defined in its superclass.

Runtime polymorphism: Also known as dynamic polymorphism, it is achieved through method overriding and dynamic method dispatch.

Compile-time polymorphism: Also known as static polymorphism, it is achieved through method overloading, where multiple methods have the same name but different parameters.There are two types of polymorphism in Java: In other words, it enables a single interface to represent different types of objects. In the context of OOP, polymorphism allows objects of different classes to be treated as objects of a common superclass. Polymorphism is derived from two Greek words, 'poly' meaning many, and 'morph' meaning forms.

By the end of this tutorial, you should have a strong understanding of how to implement polymorphism in your Java applications, making your code more flexible and reusable. Polymorphism is one of the four fundamental principles of object-oriented programming (OOP), along with encapsulation, inheritance, and abstraction. In this tutorial, we will explore Java polymorphism, focusing on method overriding and dynamic method dispatch.
