HWPF: java doubts

I have some basic doubts regarding Java as I am very new to it ,  I was 
mainly working in C before.

is byte datatype conterpart of unsigned char in C, say can i store 255 in 
a byte variable?
If yes then why is it that in LittleEndian.getunsignedByte is returning an 
int ? Cant we typecast it to byte and return.

In HWPFOutputStream class or its parent class there are no functions named  write(  ) that 
take only a byte  array.
But we r doing docStream.write(grpprl); which does this , How is it possible??


Thanks & Regards
Praveen

We use a version control system called CVS. The easiest way to get to the
files is to get the files directly through CVS. The easiest way to do this
is to download a GUI client. There is a platform independent one at
http://www.jcvs.org You sound like a CVS newbie. Well so am I. I hate CVS
with a friggin passion. Its like an ancient Unix command line utility 
thats
been mutated by radiation into a version control system.

Java has no unsigned types.  Thus if you make it a byte, you'll have to deal
with the sign.
