How can I tell if the host is little endian or big endian ? Also, does Java have byte-swap, ntoh(), and hton() functions ?

You shouldn't have to worry about endianness...  Java is the same across all platforms..

When using java to talk to non-java however, I just use my friends >>, <<, and &. (bitwise and and shift)

I have to parse a binary file, so I really need to worry about it. It's for the same reason you call ntoh() and hton() when doing socket programming.

Try using a DataOutputStream to write out an int of value 1.
Attach a DataInputStream to the other end and read the four
bytes off as four bytes.  The first byte will be 1 on some
platforms, and the fourth will be 1 on the others.

I don't think Java has any byte-swapping functions.
