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