Question

Hi there i am so sorry to bother with such a length question but i am unable to do it. I am struggling with the following question:

Once the user starts the thread by clicking a button, the program must choose a random image out of an image array, and display the image in the center. When the program starts, the user must be prompted for their name. The time must also be displayed (hh:mm) and must be part of the thread, to keep it updated. The pictures name must be displayed in the appropriate box. When the user stops the thread, the picture name must be cleared and the component in which the image was found must be set to a random color. The thread must also be stopped when the exit button is clicked.

Answer 1

Answer on question #61311, Programming & Computer Science / Java | JSP | JSF | for completion

Once the user starts the thread by clicking a button, the program must choose a random image out of an image array, and display the image in the center. When the program starts, the user must be prompted for their name. The time must also be displayed (hh:mm) and must be part of the thread, to keep it updated. The pictures name must be displayed in the appropriate box. When the user stops the thread, the picture name must be cleared and the component in which the image was found must be set to a random color. The thread must also be stopped when the exit button is clicked.
