False optimization usually. Modern 64-bit CPUs use a native 8-byte word w/ hardware support for 4-byte words. It's actually slower to use a 8-bit char/byte than a 32 or 64-bit int with one exception: storage or payload size. You're probably not dealing those latter issues here so stick to simple ints.

Code

int x=5;
byte b = (byte) x;
byte c = (byte) 300; // error, a  byte must be between 0 and 255

But like @i960 said, it's probably not going to help you much because of 32 or 64-bit word sizes in today's CPUs. It can help with file and database storage optimization though.
