public class Char
extends java.lang.Object

The Char class names the control characters because it is inconvenient to try to remember their ordinal position in the ASCII character set. The names are the standard ASCII abbreviation. We also give aliases to match common usage for some of the characters. All the other characters are easily represented within quotes and easy to remember and understand, so no special names are given to them -- except for Space which is ubiquitous and not always easy to see.

The characters are all of type char because they are used in contexts where type char is expected.
