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:

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 :
Java: | if x != 0 && y/x == 1 |
while this will cause an error if x is 0 :
Java: | if x != 0 & y/x == 1 |
