I see what you're saying.  But if that were true then the while loop would have
multiple iterations.  No?

The read and write methods are only being called once in this method for this
file.  Just confirmed with another test.

This is true because I'm sizing the buffer to the length of the file and... 

  br.read(charBuff,0,fileLength)

...reads the entire file length in the first shot.
