I have modified your code between line 41 and 62 as follows:

if (source == theMainButton) {
		resizeComponent(this);
        	         setLocation(rand.nextInt(screenSize.width-3*BUTTON_WIDTH),
        	         rand.nextInt(screenSize.height-3*BUTTON_HEIGHT));               
                  long start = System.currentTimeMillis(); // get the starting milli-seconds
             	n++;
                if(n>=8){
                JOptionPane.showMessageDialog(null, "You Clicked it " +n);
                long elapsedTimeSec = System.currentTimeMillis(); // get the stoping milli-seconds,
                elapsedTimesec1 =(double)(elapsedTimeSec - start)/1000.0; // calculate the lasting time in seconds.
                JOptionPane.showMessageDialog(null, "Took you: " + elapsedTimesec1  + " seconds."); // showing the result.
                }

hope the changes are helpful.

Im sorry i got it to display it, but it seems like the counter is off.
It shows like .987 seconds when i have been clicking it for more than like 10 seconds

[acash229]

The clock is way off the time. It takes me 3 secs to click and it shows 13 seconds.

Thank you for the help though.

If this can be fixed you will the best person alive and make me a happy man. :)
