Escape Sequence

Java allows us to have certain non-graphic characters in character constants. (non-graphic characters are those which cannot be typed directly from the keyboard, e.g, backspace, tabs, carriage return, etc.). These characters are represented with the use of an escape sequence, which is represented by a backslash(\) followed by one or more characters.

The following table gives a listing of escape sequences:

Escape Characters	Description
\t	to insert a tab in the text at this point.
\’	to insert a single quote character in the text at this point.
\”	to insert a double quote character in the text at this point.
\r	to insert a carriage return in the text at this point.
\\	to insert a backslash character in the text at this point.
\n	to insert a new line in the text at this point.
\f	to insert a form feed in the text at this point.
\b	to insert a backspace in the text at this point.

Example:

class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, world!\r\"Coderzpy\" "); 
    }
}

Output:

Hello, world!
"Coderzpy"
