The Long class wraps a value of the primitive type long in an object. An object of type Long contains a
single field whose type is long .
In addition, this class provides several methods for converting
a long to a String and a String to a long , as well as other constants and methods useful when dealing
with a long .
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).
