자바 캐릭터 타입에 대한 내용입니다..
A char is a single character, that is a letter, a digit, a punctuation mark, a tab, a space or something similar. A char literal is a single one character enclosed in single quote marks like this
char myCharacter = ‘g’;
Some characters are hard to type. For these Java provides escape sequences. This is a backslash followed by an alphanumeric code. For instance
‘\n’ is the newline character.
‘\t’ is the tab character.
‘\\’ is the backslash itself. The following escape sequences are defined:
|\”||double quote, “|
|\’||single quote, ‘|
The double quote escape sequence is used mainly inside strings where it would otherwise terminate the string. For instance
System.out.println(“And then Jim said, \”Who’s at the door?\””);
It isn’t necessary to escape the double quote inside single quotes. The following line is legal in Java
char doublequote = ‘”‘;
