On 2's complement machines (the only sort I've ever used), the additional bits are done via sign extension. This behavior should be identical to the behavior in C. Side note: I use the Java convention of converting a char to an int: char c = '\xAA'; int i; i = c & 0xFF; Works the reliably on plain-char-is-signed and plain-char-is-unsigned machines. Presuming the architecture is 8-bit-bytes (such as all my platforms are). And I'm not sure if there's caveats for 1's complement machines to worry about. Sincerely, --Eljay
