The document discusses passing parameters to an applet embedded in HTML. It provides a Java program that defines an applet class called HelloWorld2 that can accept parameter values passed from HTML. The HTML code embeds the applet and passes it three parameter values for a display name, x-coordinate, and y-coordinate. When run, the applet will display the text "Hello JohnSmith!" at coordinates 50,20.

1. QUESTION:
Write a program to Pass parameters embedding in HTML. (i.e Passing Parameters to Applets)
SOL:
CODE:
package com.p1;
import java.awt.Graphics;
import java.applet.Applet;
public class HelloWorld2 extends Applet
{
private String theDisplayString = "World";
private int theStartx = 10;
private int theStarty = 10;
public void init()
{
String tempName = this.getParameter("displayName");
String tempXString = this.getParameter("startx");
String tempYString = this.getParameter("starty");
if ((tempName!=null)&&(tempXString!=null)&&(tempYString!=null))
{
this.theDisplayString = tempName;
this.theStartx = (new Integer(tempXString)).intValue();
this.theStarty = (new Integer(tempYString)).intValue();
}
}
public void paint(Graphics g)
{
g.drawString("Hello "+theDisplayString+"!",theStartx,theStarty);
}
}

2. HTML CODE:
<title>TestAppletPage </title>
<hr>
<appletcode=HelloWorld2.classwidth=200height=100>
<param name=displayName value="JohnSmith">
<param name=startx value="50">
<param name=startyvalue="20">
</applet>
<hr>
OUTPUT:
