To Receive Credit

If you finish during Tuesday's lab, ask your TA to come over to check your program and give you credit.
Note: The TA will check your program on your computer. You do not need to print out the source code.
If you are unable during Tuesday's lab, turn in the printout of ImageViewer.java by the start of class on Wednesday.

If you finish early, get yourself checked off first! As a programming challenge (not required but recommended):

Replace the button with a File menu Open item. Add a Exit menu item as well.
