The Integer class wraps a value of the primitive type
int in an object. An object of type Integer
contains a single field whose type is int .
In addition, this class provides several methods for converting
an int to a String and a String to an
int , as well as other constants and methods useful when
dealing with an int .
Implementation note: The implementations of the "bit twiddling"
methods (such as highestOneBit and
numberOfTrailingZeros ) are
based on material from Henry S. Warren, Jr.'s Hacker's
Delight, (Addison Wesley, 2002).
