    Unhappy Problem with an array in a timer

    Hi, I have a code, which includes arrays. I i'm not an expert but as far as I know, it's supposed to work. The code is supposed to delete any non-integer characters from the textfields in the array. Unfortunately it doesn't, but i can't figure out why.
    This is the array:

    private JTextField[] textFields = {
    txtv1, txtv2, txtv3, txtv4, txtv5, txtv6, txtv7, txtv8, txtv9, txtv10,
    txtv11, txtv12, txtv13, txtv14, txtv15, txtv16, txtv17, txtv18, txtv19,
    txtv20, txtv21, txtv22, txtv23, txtv24, txtv25, txtv26, txtv27, txtv28,
    txtv29, txtv30, txtv31, txtv32, txtv33, txtv34, txtv35, txtv36,
    txtv1to12, txtv13to24, txtv25to36, txtv3to36, txtv2to35, txtv1to34,
    txtv00, txtv0, txtv1to18, txtveven, txtvzwart, txtvodd, txtv19to36, txtvrood
    };

    This is the timer:

    final Timer t3 = new Timer(5000, new ActionListener() {
    public void actionPerformed(ActionEvent e) {

    for (int t = 0; t < 51; t++) {
    if (!(textFields[t]==null)) {
    try {
    int x = Integer.parseInt(textFields[t].getText());
    } catch (Exception ex) {
    textFields[t].setText(textFields[t].getText().substring(0, textFields[t].getText().length() - 1));
    }
    }
    }

    }
    });
    t3.start();
    Can someone please tell me what's wrong with this timer?
