Your First Java Program: An Interactive Beginner Blog

Your First Java Program

Java is strict. That’s good: it teaches you to be precise. Your first win is printing a line.

Try it (safe mini-runner)

Runner: ready

This mini-runner understands System.out.println() with simple text/number output. It is made for beginners and works inside Blogger.

Ready.


      
Tip: change the text inside quotes. If you break it, you learn faster (annoying, but true).
This is not a full Java compiler. It only executes print/println statements in a safe way. For real Java, use an IDE or terminal (instructions below).

What each part means

public class Main is the container for your code.

public static void main is where Java starts running.

System.out.println prints text to the output.

If you only remember one thing: main is the start.

How to run real Java (the honest way)

Save your file as Main.java, then run:

javac Main.java
java Main

If that feels hard: you’re not dumb, Java is just being Java.
