How to write an Java Applet?

Steps to Run Your Applet:

Create a Java Program (HelloWorld.java) with the following code:

import java.applet.Applet;
import java.awt.Graphics;

public class HelloWorld extends Applet {
    public void paint(Graphics g) {
        g.drawString("Hello world!", 50, 25);
    }
}

Compile it by javac HelloWorld.java.

Create a HTML page (HelloWorld.html) to include the applet in <applet> tag as follows:

<html>
<head>
<title>HelloWorld Applet</title>
</head>
<body>
<center>
This is the HelloWorld Applet. <br>
<applet code = "HelloWorld.class" width = 150 height = 50>
</applet>
</center>
</body>
</html>
