public class NurseSystem extends JFrame
{
     
        public NurseSystem()
        {
            JMenuBar menuBar = new JMenuBar();
      JMenu fileMenu = new JMenu("File");
      JMenu editMenu = new JMenu("Edit");

      editMenu.add(ModifyFileItem);
      editMenu.add(deleteFileItem);
     
        //Add the menus to the menubar
      menuBar.add (fileMenu);
      menuBar.add (editMenu);
     
      //add the menubar to the application window
      setJMenuBar (menuBar);
     
      //Name and Detailed labels
      JLabel label1 = new JLabel("                                    ");
      JLabel label2 = new JLabel("                                      ");
 
      JLabel nurseName = new JLabel("Nurse Name",JLabel.LEFT);
      JLabel detailedInfo = new JLabel("Detailed Information");
     
      //Create a LIst

      //set component layout
            FlowLayout layout = new FlowLayout();
            Container mainWindow = getContentPane();
            mainWindow.setLayout (layout);
            //add labels to the main Window
            mainWindow.add(nurseName);
            mainWindow.add(label1);
            mainWindow.add(label2);
            mainWindow.add(detailedInfo);
       

       
       

     
       
                this.addWindowListener        (new WindowAdapter(){
                        public void windowClosing(WindowEvent e){
                                dispose();
                                System.exit(0);
                        }
                });
        }
       
        public static void main(String args[])
        {
          System.out.print("Nurse System");
                NurseSystem f = new NurseSystem();
                f.setSize(500,400);
                f.show();
        }

Code:

---

JTextArea textBox = new JTextArea();
JScrollPane myPane = newJScrollPane(textBox);
