How to run Java applets in browser (with CMD)

I know, no one uses applets now, but My Undergrad degree still have this in the syllabus!!

This is my HelloWorld.java file 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);
    }
}

This is my Hello.html file code

<html>
    <body>
        Here is the output of my program:
        <applet code="HelloWorld.class" width="150" height="25"></applet>
    </body>
</html>

Both the files are saved to desktop.

This is what I did:

  1. Open CMD
  2. Type cd desktop
  3. Type javac HelloWorld.java
  4. Open Hello.html file in Chrome, Opera, Firefox, Microsoft Edge

None of the browser runs the applet!! Normal Java (AWT) programs are running using CMD but not applet.

JDK & JRE version I am using is jdk1.8.0_201 & jre1.8.0_201 respectively.

Solution

  • Use the commands below:

    /*
<html>
<applet code="HelloWorld.class" CodeBase="" width=300 height=400></applet>
</html>
*/

    save this as "HelloWorld.html"

    c:\>javac HelloWorld.java
c:\>appletviewer HelloWorld.html
