    Default How to allow my program to keep runningwithout closing it?

    As mentioned in the title, How do I go about allowing my program to run as many times without having to close the program?

    Now, I am able to run my program but problem is whenever I click the "Start" button, it will not work because it does not clear the previous inputs.


    When I start the program for the 1st time,
    col is B row is 145
    col is B row is 161

    if I run my program (w/o closing it) again,
    col is BB row is 145145 <-
    col is BB row is 161161 <-

    How do I allow the program to run multiple times without having to close it?

    Are you talking about using a loop? That is the normal way to do the same thing over and over as many times as you want.

    whenever I click the "Start" button, it will not work because it does not clear the previous inputs.
    Why don't you clear the previous inputs?
    What statements do you use to put the values in the display area?

    Yeap. I guess it's loop I'm talking about. But how do I go about doing it?

    I tried to use setText(" "); but it doesn't work. The problem is still there.

    Which display area you meant?

    Where did you put the .setText(); ?


    JLabel lblCell = new JLabel("Cell Range: ");
    final	JTextField tfCell = new JTextField(5);
    JLabel lblDelay = new JLabel("Delay: ");
    JTextField tfDelay = new JTextField(5);

    Do these values load blank each time now?
