    why the out put is messed when the for loop is in place
    Can you describe what the messed part is now? After a few code changes, it could be acting differently than it was.

    like traped on one side
    Back to printing out the values of the balls positions. Only test with two balls to keep it simple. You might try changing the size of the window and the speed that the balls move for easier debugging.
    The thing to notice is when the ball reverses direction. What variables are used when a ball reverses direction?

    You can make assumptions and/or you can add printlns and look at the output and see if there is a pattern when a ball looks like it is "trapped on one side".
    What are the values of the balls positions when that happens?

    And I assume that the one balll moved as expected. Is that correct?
    Now run the test with two balls.

    Did you read post#30?
