Java Programming for Beginners

Master Java step by step with beginner-friendly explanations, real-world examples, and strong object-oriented programming foundations.

Java is a high-level, object-oriented language known for its "Write Once, Run Anywhere" capability thanks to the JVM.

2. Basic Program Structure

Every Java program must have at least one class and one main method.

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

3. Variables in Java

Variables are containers used to store data values defined by specific types.

int age = 22;
String name = "Dhanush";
boolean isCoder = true;

12. Object-Oriented Programming (OOP)

Java is fully object-oriented. Core pillars include Encapsulation, Inheritance, Polymorphism, and Abstraction.

// Example of a simple class in Java
class Animal {
  void eat() { System.out.println("Eating..."); }
}
