    Unhappy IndexOutOfBoundsException - HELP! DONíT KNOW EXACTLY WHAT THIS MEANS. :(

    keep getting this error, but it don’t appear from time to time, there are times that it don’t and there are times when this appears. I have a timer that is shown in the gui but I don’t use invokelater to show the timer to gui, all I do is that I use MTTextArea to make it appear in the gui. Well, I can’t point out the problem because it says there the arraylist is unknown source… I’m a beginner programmer and it’s the first time I encountered this kind of exception… please somebody explain to me what is going on? and why this exception keeps on appearing? And I don’t have an arraylist in my code by the way…


    here's the actual code that I believe where I'm getting the error: (it's not the full code though... because it is very long you might get headaches )


    public class TimeClass extends TimerTask {
    int counter;
    PImage imggo = mtApp.loadImage("Puzzle/datas/gameover.png");
    MTRectangle re = new MTRectangle(mtApp, 400, 200);
    PImage ta = mtApp.loadImage("Puzzle/datas/tryagain.png");
    final MTRectangle tryAgain = new MTRectangle(mtApp,
    (mtApp.width / 2) - 150, (mtApp.height / 2), 0, 300, 100);
    final MTTextArea yestry = new MTTextArea(mtApp, font);
    final MTTextArea noexit = new MTTextArea(mtApp, font);

    public TimeClass(int counter) {
    this.counter = counter;
    }

    private long TimeInSeconds = 0, TimeInMinutes = 0;

    @Override
    public void run() {

    try{
    TimeInSeconds++;
    if (TimeInSeconds < 10) {
    timercount.setText(" 0" + TimeInSeconds);
    } else {
    timercount.setText(" " + TimeInSeconds);
    }
    if (TimeInSeconds == 59) {

    TimeInSeconds = 0;
    TimeInMinutes++;
    timercount2.setText(TimeInMinutes + " : ");

    }

    and if you really have a free time... here's the full code... but I need to warn you that it won't run because you still need the pictures I used and the library I'm using which is mt4j ..

    Default Re: IndexOutOfBoundsException - HELP! DONíT KNOW EXACTLY WHAT THIS MEANS. :(

    Hello.
    Instead of attaching the image like this it might be better if you post the piece of your code that produced the error along with the stack trace.
    Looking at the exception its clear that you are trying to read a value at an index which is beyond the size of the array/collection.

    Syed.
