Answer 1

Collections.sort(list, implementation of comparator)

Answer 2

An alternative to writing a custom comparator would be to create your own subclass which implements Comparable and then define a compareTo method as detailed here .

I personally prefer implementing a compareTo , as it allows you to use the various sorts built into other classes, rather than being restricted to only your Comparator class.
