Collection Utilities

• The java.util.Collections class provides standard utilities for Collections.
  • List Sorting
  • Binary List Search
  • List reversing and shuffling
  • Min and Max
  • Synchonization
• 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.
