I keep getting this message when trying to run a java program that
calculates the hypotenuse of a right triangle. The program will compile,
but it won't run. Could someone please help me with this? Any help will
be greatly appreciated. Here is the code for my program:

// Exercise 6.15 Solution
// Triangle.java
// Program calculates the hypotenuse of a right triangle.

import javax.swing.*;
import java.awt.event.*;
import java.awt.*;


public class Triangle extends JApplet implements ActionListener
{
JTextField sideInput, side2Input;
JLabel sidePrompt, sidePrompt2;

public void init()
{
sideInput = new JTextField( 4 );
side2Input = new JTextField( 4 );
side2Input.addActionListener( this );
sidePrompt = new JLabel( "Enter side 1: " );
sidePrompt2 = new JLabel( "Enter side 2: " );
Container c = getContentPane();
c.setLayout( new FlowLayout() );
c.add( sidePrompt );
c.add( sideInput );
c.add( sidePrompt2 );
c.add( side2Input );
}

public void actionPerformed( ActionEvent e )
{
double sidel, side2;

sidel = Double.parseDouble( side2Input.getText() );
side2 = Double.parseDouble( sideInput.getText() );

double h = hypotenuse( sidel, side2 );
showStatus( "Hypotenuse is : " + h );
}

public double hypotenuse( double side1, double side2 )
{
double hypotSquared = Math.pow( side1, 2 ) + Math.pow( side2,
2 );
return Math.sqrt( hypotSquared );
}
}

Peter,

Thank you so much for your help. As you can see, I'm a novice in Java
programming. Thanks for being so courteous and understanding. I followed
your instructions, and my program worked perfectly.

Thanks Again,

As you can see, I'm quite the novice in Java programming, but I'm learning
more every day. I came to this site to seek help from knowledgeable people
who are eager to help the beginner. Obviously you are not one of these
people that I seek. However, I did get a courteous and excellent reply
from someone. If all you are going to do is send insulting replies, then
why do you even bother to answer? Thanks for nothing, and have a great day.

Keith
