Oops concept in Java refers to Object-Oriented Programming principles like Inheritance, Polymorphism, Encapsulation, and Abstraction.

• Inheritance allows a class to inherit properties and behavior from another class.

• Polymorphism allows objects to be treated as instances of their parent class.

• Encapsulation hides the internal state of an object and only exposes necessary methods.

• Abstraction focuses on the essential features of an object while hiding the implementation details.
