💡 What is Java?

Java is a high-level, object-oriented programming language developed by Sun Microsystems (now owned by Oracle). Known for its "Write Once, Run Anywhere" capability, Java applications are platform-independent, meaning they can run on any device that supports Java without recompilation. When you're following a Java Tutorial, understanding this core concept helps you appreciate the language's flexibility and power.

✅ Why Learn Java Programming Language?

  • Platform Independence: Java runs on JVM, making it cross-platform.
  • High Demand: Java developers are consistently in demand across industries.
  • Robust Libraries: Comes with extensive APIs and frameworks.
  • Community Support: Backed by a massive global community.

🎨 Getting Started with Java

To follow this Java Tutorial, you’ll need:

  • Java Development Kit (JDK) installed.
  • A code editor like Eclipse, IntelliJ IDEA, or VS Code.
  • Basic understanding of programming (not mandatory).

📚 Java Programming Basics

Let’s start with the basic syntax. Here's your first Java code:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
Enter fullscreen mode Exit fullscreen mode

Explanation:

  • public class HelloWorld defines a class.
  • main is the entry point.
  • System.out.println prints to the console.

⚖️ Java Data Types and Variables 

int age = 25;
double price = 99.99;
char grade = 'A';
boolean isPassed = true;
Enter fullscreen mode Exit fullscreen mode

Java has strong typing. You must define the data type of each variable.

🤠 Java Control Structures

If-Else: 

if(age > 18) {
    System.out.println("Adult");
} else {
    System.out.println("Minor");
}
Enter fullscreen mode Exit fullscreen mode

Loops: 

for(int i = 1; i <= 5; i++) {
    System.out.println("Count: " + i);
}
Enter fullscreen mode Exit fullscreen mode

🌐 Object-Oriented Programming in Java

Java uses OOP principles: Encapsulation, Inheritance, Polymorphism, and Abstraction.

Example - Class and Object: 

class Car {
    String model;

    void display() {
        System.out.println("Car Model: " + model);
    }
}

public class Main {
    public static void main(String[] args) {
        Car myCar = new Car();
        myCar.model = "Tesla";
        myCar.display();
    }
}
Enter fullscreen mode Exit fullscreen mode

🚀 Java Hands-On Projects

To Learn Java Programming Language efficiently, you must build projects. Here are a few beginner-level ideas:

  1. Calculator App: Use Java Swing or JavaFX to create a simple GUI calculator.
  2. To-Do List: Console-based app with file storage.
  3. Student Database System: Add, update, delete records using Java and JDBC.
