The java.util.Collections class provides standard utilities for Collections.

Sorting makes use of the Comparator interface, which a programmer implements to determine how objects of a particular type are to be ordered.
The Syncronization methods return thread-safe collections that are backed by a specified collection. Note that iteration is still not thread safe in this case.
