Re: Bitwise operators

On Sat, 22 Feb 2003 19:16:45 -0500 (EST), Henri Yandell was overheard saying:
|  Check out java.math.BigInteger.
|  
|  As well as being 'some kinda big number holder' it's also a great bit
|  handler. Not what you'd expect of it from the name.

|  A hidden secret.

A colleague pointed java.util.BitSet out to me the other day.  I don't
know how suitable it is for embedded platforms, but it's very handy
for everyday bit operations.  Even though it works like a collection
of booleans, it's stored as bits so you get a minimal memory
footprint, and you get bitwise operations too: and, andNot, or, xor.

After mentioning it to me, I did some research and turned up a recent
JDC Tech Tip that talks about BitSet:
