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

Open in new window

HTML:

<html>

<body>
<h2>My first Java program</h2>
	<applet code="Helloworld.class" height="200" width="250">
	</applet>
</body>
</html>

I have also used this java with no result.

 import java.applet.Applet;
 import java.awt.*;
 
 class Helloworld extends Applet{
	 public static void main(String args[]){
	     System.out.println("Hello World");
	  }
 }

Applets are not simple java programs. There is a tutorial you should read

        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                public void run() {
                    JLabel lbl = new JLabel("Hello World");
                    add(lbl);
