I added the homework tag and formatted the code.

What do you've got? and what are you passing where?
Please post your code snippet as we want to make sure you do your homework yourself.

See this Java Tutorial[^].

sorry, the above link does not exist any more. Think Oracle have updated it :

http://download.oracle.com/javase/tutorial/collections/algorithms/index.html

Either way the answer lies in the Comparable or Comparator interface.
