Is it possible to find out the difference between two file using java. Eg. I have a file c:a.txt and d:a.txt. I need to figure out if these two files are essentially the same. Is there any standard api that can do this. e.g using checksum or some other mechanism. File.compareTo/equal method aren't of help. Any inputs on this issue would be immensely helpful.

How about opening a stream to each file, reading from each stream one byte at a time and comparing each and every byte?
