char is a keyword. It defines a character primitive type.
char can be created from character literals and numeric representation. Character literals consist of a single quote character (
') (ASCII 39, hex 0x27), a single character, and a close quote (
'), such as
'w'. Instead of a character, you can also use a unicode escape sequences, but there must be exactly one.
|char variable name1 = 'character1';|

The nominal wrapper class is the
java.lang.Character class when you need to store a
char value but an object reference is required.
