![]() ![]() For example, if you want to put quotes within quotes you must use the escape sequence, \", on the interior quotes. When an escape sequence is encountered in a print statement, the compiler interprets it accordingly. ![]() Insert a backslash character in the text at this point. Blanks, horizontal and vertical tabs, carriage returns, formfeeds, and newlines, collectively called white space, are ignored except as they serve to separate. That includes, of course, spaces and tabs as well as 19. Insert a double quote character in the text at this point. A whitespace is any Unicode code point other than n or r for which Character.isWhitespace is true. Insert a single quote character in the text at this point. You can use these escape sequences within a string. Insert a form feed in the text at this point. There are five special whitespace characters with escape sequences, as shown in Table 9-1. Insert a carriage return in the text at this point. Insert a newline in the text at this point. Insert a backspace in the text at this point. The following table shows the Java escape sequences: Escape Sequences Escape Sequence Returns a String object representing the specified character value that is, a one-character string.Ī character preceded by a backslash (\) is an escape sequence and has special meaning to the compiler. ![]() Returns the uppercase or lowercase form of the specified char value. In the name or value, Java language escape sequences t, n, r, f, ,, , and uxxxx are recognized and converted to single characters. The same can be achieved with Java Unicode characters equal sign can be replaced with java Unicode u003d value and white space for u0020 include special. Useful Methods in the Character Class Methodĭetermines whether the specified char value is a letter or a digit, respectively.ĭetermines whether the specified char value is white space.ĭetermines whether the specified char value is uppercase or lowercase, respectively. For a complete listing of all methods in this class (there are more than 50), refer to the You may use either whitespace characters or tabs for indentation, but whatever you use must be consistent throughout the entire. The following table lists some of the most useful methods in the Character class, but is not exhaustive. Note: The Character class is immutable, so that once it is created, a Character object cannot be changed. ![]()
