You can do boolean operations on ints or ints, many bits at a time using &, |, ^ and ~. With boolean, you can only process one bit at a time, typically with !, && and ||. For bit strings longer than 64 bits, use java.util.BitSet. Even experienced programmers sometimes lapse into redundant newbie-like baby talk when using booleans. To avoid that embarrassement .
