    Default Re: Draw same image in random position with time delay

    A couple of techniques:
    Keep a list of the locations to draw the images, add to the list and use that list in the drawing method.
    Define a BufferedImage, draw the next image on that image and draw that image in the painting method.
    If you don't understand my answer, don't ignore it, ask a question.
