"Character" Class with Unicode Utility Methods

This section provides an introduction on 'Character' class static methods added since J2SE 5.0 as Unicode utility methods.

Since designers of J2SE 5.0 did not change the internal storage size for the "Character" class, it can not be used to support Unicode supplementary characters in the range of U+0000 to U+10FFFF. So you should avoid using "Character" class to represent a single Unicode character in the future to make your application Unicode-friendly.

However designers of J2SE 5.0 did add a number of static methods in the "Character" class as utility methods to help Unicode character processing. So take a look at some of them:

See the next section for a tutorial example on how to use "Character" class static methods.
