I was wondering if anyone can help me to understand 3 by 8 decoders. I have to write a program that simulates a 3 by 8 decoder and so far it only passes black box testing. This means I basically did "If input is _ and enable is _, then output is _. I would like to expand but I am not good at using java.
I will post again later after I have had more time to work with it. Any tips would be great.

Thanks
