GUI problem

I created a GUI that extends JFrame. The GUI has several textfields, buttons, labels and lists. The problem arises when i minimise the window and then maximise it. The textfields stay in place but the list, labels and buttons stick to the top of the window after maximising! Please Help
this is the part of the code where i add a list, label and button for example:

Code Java:

---

  l = new List();
                                                   l.setSize(250, 200);
 
                                                   l.setLocation(500, 250);
                                                   l.setVisible(true);
                                                   l.setFocusable(true);
                                                   M.add(l);//was M
                                                   l.setFont(new Font("sansserif", Font.BOLD, 15));//set the txt font n size
 
                                                   patientListTitle=new Label("PID:         Patient's Name:");
                                                   patientListTitle.setSize(200, 50);
 
                                                   patientListTitle.setLocation(500, 200);
                                                   patientListTitle.setForeground(Color.BLACK);
                                                   patientListTitle.setBackground(Color.white);
                                                   patientListTitle.setVisible(true);
                                                   patientListTitle.setFocusable(true);
 
                                                  M.add(patientListTitle);//was M
 
 
                                                   Select.setSize(50, 25);
                                                   Select.setLocation(500, 580);
                                                   Select.setVisible(true);
                                                   Select.setFocusable(true);
                                                   M.add(Select);//was M
 
                                                   Select.addActionListener(new ActionListener(){
                                                    public void actionPerformed(ActionEvent e) {
                                                                System.out.println("Select Button clicked");
                                                                // ADD STUFF HERE :D
 
                                                                getIndexedItem=l.getItem(l.getSelectedIndex());
                                                                System.out.println(getIndexedItem);
                                    try {
                                        deletePatient(getIndexedItem, l.getSelectedIndex());
                                    } catch (SQLException ex) {
                                        Logger.getLogger(javaapplication2.class.getName()).log(Level.SEVERE, null, ex);
                                    } catch (ClassNotFoundException ex) {
                                        Logger.getLogger(javaapplication2.class.getName()).log(Level.SEVERE, null, ex);
                                    }
 
 
                                                            }
                                                    });
                                                  repaint();
                            try {

                                                                           repaint();

Is this:

Code java:

---

l = new List();

---

supposed to be a JList?

If you really want to use coordinates, I would suggest the layout I made. I attached text documents of the java classes (since I cannot attach .java files). Save them as .java files instead of .txt files, compile them, and run them to see how it works. Very simple once you get the hang of it.

All I ask is that you don't claim it as your creation.

There are a few "bugs" in it, as in some of the methods don't work exactly as expected and some are incomplete. If you feel like completing them or fixing them, tell me and I'll add you on the credit if you get them working.

With the information provided it is difficult to ascertain what the exact problem is, but my guess is along the same lines as aussiemcgr. Are you setting your layout to null? If so, do not use this approach. Use a standard layout that Swing provides. See A Visual Guide to Layout Managers

Thank you all. What I am doing is that i created a public class that extends Jpannel and I am adding my components to it. It works perfectly before minimising the window:

after minmising the window:

I did not use any grids or layout organizations. Just added the components and set the coordinates. Is that the problem?

list is not a Jlist.

Well then I'm confused. The List class (List (Java Platform SE 6)) has no setSize method, setLocation method, setVisible method, setFocusable method, or setFont method. The JList class however (JList (Java Platform SE 6)) has all of those.
