Literal Formats for Characters
This section describes literal formats for character values of char data type: single characters or escape sequences enclosed in single quotes.
Java supports literals for the character data type, char, in several formats described below
Character Literal - Basic rules on character literals:
- A character value in "char" data type can be represented as a single character enclosed in single quotes,
like 'A', '1', ' ' and '"'.
- Special characters ' and \ must be escaped with \, like '\'' and '\\'.
- Control characters must be entered as escape sequences, like '\t', '\n' and '\r'.
- Double-byte Unicode characters can be entered as Unicode sequences, like '\u0041' and '\u03C9'.
- Decimal sequences can also be used, like '\101' and '\969'.
