No, a long is eight bytes in Java.

A long is 64 bits in size.
Also remember that all numeric types are signed.

You may want to look at BigInteger or BigDecimal if you're looking for arbitrary precision.

Actually, a char is an unsigned 16-bit number, which can be very handy at times.

Unsigned variables would probably be close to the top of my Java wishlist.

Well, as you no doubt know, you can unsign them using the >>> (or is it <<<) operator.

An unsigned kweyword would be nice tho
