What are the main principles of OOP in Java?

The main principles of OOP in Java are Encapsulation, Inheritance, Polymorphism, and Abstraction.

Can you explain Encapsulation with an example?

Sure! Encapsulation is the bundling of data and methods that operate on that data within a single unit, like a class. For example, a class Car can have private attributes like speed and fuel, and public methods like accelerate() and refuel() to manipulate those attributes.

What about Inheritance?

Inheritance allows a new class to inherit properties and methods from an existing class. For instance, if you have a class Vehicle, you can create a subclass Car that inherits from Vehicle, gaining its attributes and behaviors.

How does Polymorphism work in Java?

Polymorphism allows methods to do different things based on the object it is acting upon. In Java, this can be achieved through method overriding and method overloading.
