Java Language Literals Character literals


Character literals provide the most convenient way to express char values in Java source code. A character literal consists of:

  • An opening single-quote (') character.
  • A representation of a character. This representation cannot be a single-quote or a line-break character, but it can be an escape sequence introduced by a backslash (\) character; see Escape sequences in literals.
  • A closing single-quote (') character.

For example:

char a = 'a';
char doubleQuote = '"';
char singleQuote = '\'';

A line-break in a character literal is a compilation error:

char newline = '
// Compilation error in previous line
char newLine = '\n';  // Correct
