    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    Please explain what the code does when it is executed and what you want it to do differently.
    If you don't understand my answer, don't ignore it, ask a question.

    It is too fast and I want it every second to display 60 . 60 or any other number close to that

    but the numbers in the bottom are adding up very fast and the blue and black are supposed to move a lot slower across the screen

    By the way, this is from the tutorial: https://www.youtube.com/watch?v=VE7ezYCTPe4

    Thanks so much I have been stuck on this for a while

    It is too fast
    Where in the code is time considered and used to change the display? Try changing the values it is using to slow down the movement.
    Do some experimenting.

    Please investigate the use of javax.swing.Timer to control the animation or activity in a Swing application.
