Answer 1

You should test Strings for equality using equals(), not ==.

if ("quit".equals(hex)) {

Expression hex.equals("quit") is correct too, it's good convention to prefer constant.equals(variable) form for better null safety.

Also note, you specified

I want it to break when the user types "break" into the console

but you are comparing the variable hex against a different string. The code above will break (i.e. get out of the loop) if the user types "quit" and not "break".
