Escape sequences for Java char type

Escape sequences are for characters that are impossible to enter directly.

To enter the single quote character itself, you 'escape' it by placing a backslash in front of it.


public class Main {
  public static void main(String[] argv) {
    char ch = '\'';

    System.out.println("ch is " + ch);

  }
}

The output generated by this program is shown here: 


ch is '

The following table shows the character escape sequences.

Escape Sequence of Java char

Escape SequenceDescription
\dddOctal character (ddd)
\uxxxxHexadecimal UNICODE character (xxxx)
\'Single quote
\"Double quote
\\Backslash
\rCarriage return
\nNew line (also known as line feed)
\fForm feed
\tTab
\bBackspace

'\n' is for the newline character. For octal notation use the backslash followed by the three-digit number. For example, '\141' is the letter 'a'. For hexadecimal, you enter a backslash-u (\u), then four hexadecimal digits. For example, '\u0061' is the ISO-Latin-1 'a'.
