Object-Oriented Programming (OOP) in Java 🧍‍♂️🧍‍♀️

Intermediate

Java is inherently object-oriented, emphasizing concepts like classes, objects, inheritance, encapsulation, polymorphism, and abstraction.

Classes and Objects:

  • Classes are blueprints defining properties (fields) and behaviors (methods).
  • Objects are instances of classes.

Example:

public class Car {
    String color;
    void drive() {
        System.out.println("Driving!");
    }
}

Car myCar = new Car();
myCar.color = "Red";
myCar.drive();

Inheritance: allows creating new classes based on existing ones, promoting reusability. Encapsulation: hides internal state with private fields and public methods. Polymorphism: enables methods to behave differently based on the object type.

Mastering OOP is crucial for designing modular, maintainable, and scalable Java applications.
