i am trying to read sets of bytes from a file into a 2d array.  my loop looks like this:

for ( int i = 0; i < numOfSets; i++) {
  theSets[i][0] = read in part of Set1;
  theSets[i][1] = read in part of Set1;
                     .
                     .
}

however, once the loop is finished, i only have the last set of bytes and its parts filling the whole array.

perhaps you can help me with another question.  how do i write to a file a certain number of bytes into it.  i know DataInputStream has skipbytes but i don't see anything like that for DataOutputStream.

You need to use RandomAccessFile.
