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
