Logic. Something that is occasionally lost to the entire world, or so it would seem.

when programming in Java sometimes we need to compare two values, this brings logic into the equation. We have to deal with logical and's, or's, not's and exclusive or's; these might sound a little complicated but with a nice cheat sheet reference guide you too can master the art of logic in programming. You will find yourself using this logic a lot in programming.

Logical && (AND)

True && True = TRUE

True && False = FALSE

False && True = FALSE

False && False = FALSE

Logical || (OR)

True || True = TRUE

True || False = TRUE

False || True = TRUE

False and False = FALSE

Logical ! (NOT)

! True = FALSE

! False = TRUE

Exclusive ^ (OR)

True ^ True = FALSE

True ^ False = TRUE

False ^ True = TRUE

False ^ False = FALSE
