Sorry for the frantic subject line, but i have two short hours left before I am flushed down the perverbial toilet.
This applet plays a few audio clips. I need it to run as an applicaton, too. I don't know how to do that. Can someone be my hero and adjust the code acordingly? Thank You.

import Chapter8.MyFrameWithExitHandling;
import java.applet.*;
public class Lab14_1 extends JApplet implements ActionListener
// Delcare Audio Files
protected AudioClip playAudio;
protected AudioClip loopAudio;
protected AudioClip stopAudio;
// Declare Buttons
private static JButton jplay = new JButton("PLAY");
private static JButton jloop = new JButton("LOOP");
private static JButton jstop = new JButton("STOP");
public void init()
JPanel p = new JPanel();
p.setLayout(new FlowLayout());
// Register Listeners
public void actionPerformed(ActionEvent e)
// Get the file name
String filename = null;
if (e.getSource() == jplay)
filename = "Chapter14/Chimp.wav";
else if (e.getSource() == jloop)
filename = "Chaper14/Chimp.wav";
if (e.getSource() == jstop)
public AudioClip createClip(String filename)
// Get the URL for the file name
URL url = this.getClass().getResource("Chimp/" + filename);
// Return the audio clip
return Applet.newAudioClip(url);
public static void main(String [] args)
// Create a frame
MyFrameWithExitHandling frame = new MyFrameWithExitHandling(
"Lab14_1 Application");
// Crate an instance of the applet
Lab14_1 applet = new Lab14_1();
// Add applet to the fray
frame.getContentPane().add(applet, BorderLayout.CENTER);
// Invoke init() and start()
// Display the frame

A Java class named "Lab14_1" huh? Will I be getting into trouble with your computer science teacher?
Converting an applet into a frame is routine.
Extend JFrame instead of JApplet.
Applet's have an "init" method, frame's have a constructor. Therefore, code a constructor and move the "init" code into it (or call your "init" method from the new constructor).
Applet's handle sizing, a frame doesn't. Therefore, you need to pack the frame. Add "this.pack();" as the last line of your new constructor.
I think applet's and frame's have different default layout managers. Therefore, make sure you explicitly set the layout manager to what you need. (You've already done that.)
That's about it. To make "Lab14_1" an application, give it a main method. In the main method create an instance of "Lab14_1" and show it.
If you want "Lab14_1" to be EITHER a frame or an applet, then have "Lab14_1" sub-class from JPanel. Then create an applet class that adds a new instance of your JPanel class to itself, and also create a JFrame class that adds a new instance of your JPanel class to itself. That way "Lab14_1" stuff can be done inside an applet or inside a frame.
I agree. Here's the link:
