No need for all caps. Also it is not relay a button or signal char but 2 of them. 1st AND is not just "&" but "&&" and OR is "||". I am a bit worried that the reason for needing this so quickly is that you are writing a test. However i will assume the best for now. You may wont to check out some of the tutorials we have on java like: http://www.compsci.ca/v3/viewtopic.php?t=9576 |

I just wanted to add that there is also & and | operators in Java. && and || are short-circuit while & and | are not. x && y <- if x is false, then y is not executed (because there is no need to, the result of the && will be false) x || y <- if x is true, then y is not executed This means that doing this is safe :
while this will cause an error if x is 0 :
