Getting Started with Java: First Program (Hello, World!)

 

🧠 What Is "Hello, World!"?

It's a basic program that does one thing: prints the message Hello, World! to the screen. But more importantly, it introduces you to the structure of a Java program.

//Code

public class HelloWorld

{

    public static void main(String[] args)

    {

          System.out.println("Hello World!");

     }

}

🛠 How to Run It

1. Open a code editor (like VS Code or just Notepad).

2. Save the file as HelloWorld.java.

3. Open Command Prompt (or Terminal).
