Please check my java applet

**mark.7100** · 07-21-2008, 04:20 PM

i don't understand why i am able to compile it but not to run it. Here's my code:
import javax.swing.*;

public class ASampleGUIProgram
{
public static void main(String[] args)
{
String appleString;
appleString = JOptionPane.showInputDialog("Enter number of apples:");

int appleCount;
appleCount = Integer.parseInt(appleString);

String orangeString;
orangeString = JOptionPane.showInputDialog("Enter number of oranges:");
int orangeCount;
orangeCount = Integer.parseInt(orangeString);

int totalFruitCount;
totalFruitCount = appleCount + orangeCount;

JOptionPane.showMessageDialog(null, "The total number of fruit = " + totalFruitCount);

System.exit(0);
}
}

and this is the html code:

<html>
<head>
<title>ASampleGUIProgram</title>
</head>

<body>

<center>
<H1 >Applet Title</H1>
<applet code="ASampleGUIProgram.class" width="200" height="200"> </applet>
</center>
</body>
</html>

please check it. thanks!!!

Are there any error messages in the Java Console when you load the html into a browser? Copy and paste them here.

You need to read up on writing Applets:
Applets extend the Applet class
The main() method is NOT used.
System.exit(0); is NOT allowed in applets.

What you've written should be executed by:
java ASampleGUIProgram

thanks! it did work just by running it using:
java ASampleGUIProgram

i just copied it from a book. anyway, how can you change it so that it will run the way i want it to be? That is by using the appletviewer command

If you want to convert the program to an Applet, you need to read about how to write an applet. Sun's tutorial would be one place to start. For code sample, use Google or search on this forum.
