🚀 Introduction: Why Learn Java?

Java has been a dominant force in the programming world for over two decades. From enterprise software to mobile apps (Android), Java powers millions of applications around the globe. But what makes Java so special and widely adopted?

Let’s break down the core features of Java that have stood the test of time.

✅ 1. Simple and Easy to Learn

Java is designed to be easy to understand and use. It removes complex features from languages like C/C++ such as pointers, operator overloading, and multiple inheritance (using classes).

📌 Why it matters:

• Developers can start coding faster.
• Easier to maintain and debug code.

Example:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, Java!");
    }
}

✅ 2. Object-Oriented Programming (OOP)

Java is object-oriented (except for primitive types), which helps in organizing complex programs through reusable objects and classes.

📌 OOP principles Java supports:

• Encapsulation
• Inheritance
• Polymorphism
• Abstraction

Example:

class Car {
    private String brand;
    public Car(String brand) {
        this.brand = brand;
    }
    public void drive() {
        System.out.println(brand + " is driving...");
    }
}
