Polymorphism and interfaces are fundamental concepts in Java's object-oriented programming paradigm, enabling flexibility, reusability, and extensibility in code. Polymorphism allows objects of different classes to be treated as instances of a common superclass or interface, while interfaces define contracts that classes must adhere to.
Polymorphism in Java
Polymorphism means "many forms" and allows the same method or object to behave differently based on the context. It is categorized into two types:
Compile-Time Polymorphism
This is achieved through method overloading, where multiple methods in the same class share the same name but differ in parameters (number, type, or order). The method to be invoked is determined at compile time.

- Multiple inheritance brings with it the potential for name conflicts. If, for example, theSoakable and Scrubable interfaces both declare a methodnamed dryOff(), classes that implement both Soakable andScrubable would inherit dryOff() twice. IfdryOff()has different signatures in both interfaces, then the class would inherit twooverloaded names, and ...
