    import java.awt.*;

    public class TimetableAdmin extends JFrame implements ActionListener
    {

    private JTextField routeTxt, rTime1Txt, rTime2Txt, rTime3Txt;
    private JTextfield route2Txt, r2Time1Txt, r2Time2Txt, r2Time3Txt;
    private JLabel routeLbl, timeLbl;

    private JButton saveBtn, backBtn;

    private JPanel timetablePanel, buttonsPanel;

    private Container c;

    public TimetableAdmin( )
    {
    super("Timetabl e Admin");

    Container c = getContentPane( );
    FlowLayout flow = new FlowLayout();
    c.setLayout(flo w);


    timetablePanel = new JPanel();


    buttonsPanel = new JPanel();

    setSize(500, 400);


    routeTxt = new JTextField(10);
    rTime1Txt = new JTextField(5);
    rTime2Txt = new JTextField(5);
    rTime3Txt = new JTextField(5);

    routeLbl = new JLabel("Route:" );
    timeLbl = new JLabel("Dep. Time:");

    saveBtn = new JButton ("Save");
    saveBtn.addActi onListener(this );
    backBtn = new JButton ("Back");
    backBtn.addActi onListener(this );

    timetablePanel. add(routeLbl);
    timetablePanel. add(routeTxt);
    timetablePanel. add(timeLbl);
    timetablePanel. add(rTime1Txt);

      Just read first the action-events, have some experiments and embed...

      Algorithm:Exper iment....

      After all initialization have made,
      Add an actionListeners to you textfields...
      After you have it, call the method were the manipulation of the values(converti on) that exists in the textfield will be transfered in the array....

      When you press 'enter', the actionListener will be triggered and do what is inside of it ( the statements ( method calling ))....

      Sukatoa...
