my dad wants me to make a timer (similar to a bleep test) to help him with his swimming lessons basicly it counts down from 20 bleeps then counts down from 19 bleeps,18 bleeps and so on so far ive got this


i think the problem lies in the for loop i can't quite get them and also will this run on windows mobile.

i'd just like to add some more information, Sorry i couldn't find the edit button. The code itself runs ok its just when i press the button that it starts to crash I think it goes into a stage of permanent loop. Also the pocket pc i plan to run it on is an acer n35.

Hi George!

To begin with the most important the edit butten is in the line where it says "posted November...", the pen and paper icon:


Your code has two things to be improved, one is easy:
in your action performed method it says:
time.setText("i");

in the i-loop.


The code does not crash - it only lasts 20 secs (minimum) until the frame displays a giant "i".


After you fixed that, you again will wait for 20 secs to see a giant "1" then.

The frame will not be updated just be setting the text to a different number. The loop loops, but the numbers in between are not displayed. Using repaint() doesn't help.

More difficult part:
You will need to put this Timer-loop into an own thread.

There is also something strange with the layout, normally you add a panel to a frame and the button and label to the panel.


How did Dory sing?

"Keep on swimming, keep on swimming, keep on swimming, swimming, swimming...".
Yours,
Bu.
