I'm assuming you meant to call the methods getDimX() rather than try to get a field named getDimX (same thing for getDimY). I don't know why you're trying to print out setDimY, usually set denotes void method which allows you to set a variable's value.

thank u very much for ur help,however, i still have some errors and i'll post them
