? What is the significance of the extends keyword in Java OOPs

The extends keyword in Java signifies inheritance, allowing a subclass to inherit fields and methods from a superclass. It enables code reusability, promoting the hierarchical organization of classes, where subclasses can extend the functionality of their superclass while adding their unique features.

?How does polymorphism manifest in Java OOPs

Polymorphism in Java refers to the ability of objects to take multiple forms. It is achieved through method overriding and method overloading. Method overriding occurs when a subclass provides a specific implementation of a method that is already defined in its superclass. Method overloading, on the other hand, involves defining multiple methods in a class with the same name but different parameters, enabling the selection of the appropriate method based on the context of invocation.
