OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i
