Can anyone explain why I get a compiler error from the byte values but not from the int values:

Thanks-
Zac

because in the statement
byte b2 = -b;
the b is promoted to an int because of the unary - sign, thus -b will be of type int which is not assignment compatible with a byte...
See 15.15.4 Unary Minus Operator -

You are correct sir... and by the way... are you going to have some sort of celebration when you hit 2000 posts, kindof like the millenium... maybe you could have some tequila to go along with the JavaRanch cowboy thing...
