We will be covering a wide range of topics including QA manual testing, automation testing, Selenium, Java, Jenkins, Cucumber, Maven, and various testing frameworks.

Polymorphism in Java

Polymorphism in Java refers to the ability of an object to take on multiple forms. It allows objects of different classes to be treated as if they are of the same class, thereby providing a flexible and extensible design for object-oriented programming.

In Java, polymorphism can be achieved through two mechanisms: method overloading and method overriding.

Method overloading is when two or more methods in the same class have the same name, but different parameters. This allows the same method name to be used for multiple purposes, and the correct method is called based on the arguments passed to it.

Method overriding, on the other hand, is when a subclass provides a specific implementation of a method that is already defined in its superclass. This allows the subclass to provide a specialized version of a method while maintaining the same method signature as its superclass.

Polymorphism is a key concept in object-oriented programming and is widely used in Java programming to create flexible and reusable code.
