    add("Center", middle);]

    [setResizable(false);
    setVisible(true);
    }
    //
    public void actionPerformed(ActionEvent e) {
    if (e.getSource() == list) {
    information.setText(LibraryData.listAll());
    } else {
    String key = trackNo.getText();
    String name = LibraryData.getName(key);
    if (name == null) {
    information.setText("No such track number");
    } else {
    information.setText(name + " - " + LibraryData.getArtist(key));
    information.append("\nRating: " + stars(LibraryData.getRating(key)));
    information.append("\nPlay count: " + LibraryData.getPlayCount(key));
    }
    }
    }

    [code=java] private String stars(int rating) {
    String stars = "";
    for (int i = 0; i < rating; ++i) {
    stars += "*";
    }
    return stars;[/java]
    }
    }

    This is meant to be coding for a jukebox application

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    Post the program's output.
    If you don't understand my answer, don't ignore it, ask a question.

    No. The code needs to be wrapped in code tags:

    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    It should look like this:
           Thread appThread = new Thread() {
               public void run() {
                   try {
                       SwingUtilities.invokeAndWait(doHelloWorld);
                   }
                   catch (Exception e) {
                       e.printStackTrace();
                   }
                   System.out.println("Finished on " + Thread.currentThread()); //Finished on Thread[Thread-0,5,main]
     
               }
           };
           appThread.start();

    What specific questions do you have about the code?

    i just need to explain how all the codes work in this application.

    for example
    // import the classes of the abstract windows toolkit and swing to enable us to use
    //components like buttons
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;

    Please edit the post and wrap the code in code tags.

    If you have questions about parts of the code, post them. "How does it all work" is too general a question.

    Have you looked in the tutorial: The Really Big Index
