Remarks
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.
<!-- Android-removed: paragraph on ValueBased
This is a value-based class; programmers should treat instances that are #equals(Object) equal as interchangeable and should not use instances for synchronization, or unpredictable behavior may occur. For example, in a future release, synchronization may fail. -->
Implementation note: The implementations of the "bit twiddling" methods (such as #highestOneBit(int) highestOneBit and #numberOfTrailingZeros(int) numberOfTrailingZeros) are based on material from Henry S. Warren, Jr.'s Hacker's Delight, (Addison Wesley, 2002).
