I have my code pretty much figured out but need a little hel

I have my code pretty much figured out but need a little help with the formatting of it.

I want my JOption popup to be a plain message with just the OK button on it. What do I need to do to fix that. Also, for some reason I am gettting a -1 autofilled in it and want it to be blank to enter my information.

Also, I want my add Course and Close course to be in the very bottom RIGHT of the page but I can\'t seem to get them in the correct location with a small space between them.

Here is the code that I have so far..Any ideas on how to fix it.

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class Labs extends JFrame {

  

private DefaultListModel courses;

private JList list;

  

public Labs()

{

JPanel p1=new JPanel();

p1.setLayout(new GridLayout(2,2));

p1.add(new JButton (\"Add Course\"));

  

  

// create a DefaultListModel to store courses

courses = new DefaultListModel();

  

// create a JList for courses DefaultListModel

list = new JList( courses );

JButton jbtAddCourse=new JButton(\"Add Course\");

jbtAddCourse.addActionListener(

new ActionListener() {

@Override

public void actionPerformed( ActionEvent event )

{

// prompt user for new course\'s name

String name = JOptionPane.showInputDialog(

Labfive.this, \"Enter Course\",JOptionPane.PLAIN_MESSAGE);

  

// add new course to model

courses.addElement( name );

}

}

);

  

// create JButton for removing selected course

JButton jbtcloseButton = new JButton( \"Close\" );

  

jbtcloseButton.addActionListener(

new ActionListener() {

@Override

  

public void actionPerformed( ActionEvent event )

{

// exit program

}

}

);

  

// lay out GUI components

JPanel inputPanel = new JPanel();

inputPanel.add( jbtAddCourse );

inputPanel.add( closeButton );

  

Container container = getContentPane();

container.add( list, BorderLayout.CENTER );

container.add( inputPanel, BorderLayout.SOUTH );

  

} // end JList constructor

  

public static void main( String args[] )

{

  

Labs frame= new Labs();

frame.setTitle(\"Labs\");

frame.setSize(400,300);

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

}

}
