ASAP PLEASE !!!
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class CheckLibrary extends JFrame
implements ActionListener {
[code=java] JTextField trackNo = new JTextField(2);
TextArea information = new TextArea(6, 50);
JButton list = new JButton("List All Tracks");
JButton check = new JButton("Check Track");
public CheckLibrary() { [/java]
setLayout(new BorderLayout());
setBounds(100, 100, 400, 200);
setTitle("Check Library");
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
JPanel top = new JPanel();
top.add(new JLabel("Enter Track Number:"));
top.add(trackNo);
top.add(check);
top.add(list);
list.addActionListener(this);
check.addActionListener(this);
add("North", top);
JPanel middle = new JPanel();
information.setText(LibraryData.listAll());
middle.add(information);
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.

are the changes i made what you asked for?

**Norm** · December 1st, 2013, 08:52 AM

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?

**Uchihamontana** · December 1st, 2013, 09:02 AM

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
