Steps to run applet on web browser (connect applet program to html) using Eclipse

Question

Hi friends I am new to Java. I am trying to display applet on web browser using Eclipse.

Code:

import java.applet.*;

import java.awt.*;

public class AppletDemo extends Applet{

    String msg="hello";

    public void init(){

        msg=getParameter("message");

    }

     public void paint(Graphics g){

        g.drawString(msg,80,80);

    }

}

Applet Tag:

<!DOCTYPE html>

<html>

<head>

<meta charset="ISO-8859-1">

<title>Insert title here</title>

</head>

<body>

<applet code="AppletDemo.class"width="350"height="350">

<param name="message"value="Welcome to the world of Applet">

</applet>

</body>

</html>

Output should be "Welcome to the world of Applet" but when I run it, no value is getting displayed.

i got output in console is:

you can use this code ..


              import java.applet.Applet.*;
              import java.applet.*;
            import java.awt.*;
            public class Demo4 extends Applet
               {
                 public void paint(Graphics g)
              {
                  Font f=new Font("calibri",Font.BOLD,50);
                  g.setFont(f);
                 g.setColor(Color.red);
                g.fillRect(0,0,1400,300);
               g.setColor(Color.yellow);
               g.fillRect(0,300,1400,600);
               g.setColor(Color.green);
               g.drawString("Welcome to the world of applet",100,200);  
               }
              }
                /*<applet code="Demo4.class" WIDTH=20 HEIGHT=20>
              </applet>*/

Here thre is no need to make applet tag direct run this code..u have to foloow these rule to run

for compile- javac Demo4.java for run- appletViewer Demo4.java

you get your ans easily..and don,t forget to include commen lines of applet these are the main lines
