The Character class wraps a value of the primitive type char in an object. An object of type Character contains a single field whose type is char.

In addition, this class provides several methods for determining a character's category (lowercase letter, digit, etc.) and for converting characters from uppercase to lowercase and vice versa.

Character information is based on the Unicode Standard, version 4.0.

The methods and data of class Character are defined by the information in the UnicodeData file that is part of the Unicode Character Database maintained by the Unicode Consortium. This file specifies various properties including name and general category for every defined Unicode code point or character range.

The file and its description are available from the Unicode Consortium at:

Unicode Character Representations

The char data type (and therefore the value that a Character object encapsulates) are based on the original Unicode specification, which defined characters as fixed-width 16-bit entities. The Unicode standard has since been changed to allow for characters whose representation requires more than 16 bits. The range of legal code points is now U+0000 to U+10FFFF, known as Unicode scalar value. (Refer to the definition of the U+n notation in the Unicode standard.)

The set of characters from U+0000 to U+FFFF is sometimes referred to as the Basic Multilingual Plane (BMP). Characters whose code points are greater than U+FFFF are called supplementary characters. The Java 2 platform uses the UTF-16 representation in char arrays and in the String and StringBuffer classes. In this representation, supplementary characters are represented as a pair of char values, the first from the high-surrogates range, (\uD800-\uDBFF), the second from the low-surrogates range (\uDC00-\uDFFF).

A char value, therefore, represents Basic Multilingual Plane (BMP) code points, including the surrogate code points, or code units of the UTF-16 encoding. An int value represents all Unicode code points, including supplementary code points. The lower (least significant) 21 bits of int are used to represent Unicode code points and the upper (most significant) 11 bits must be zero. Unless otherwise specified, the behavior with respect to supplementary characters and surrogate char values is as follows:

In the J2SE API documentation, Unicode code point is used for character values in the range between U+0000 and U+10FFFF, and Unicode code unit is used for 16-bit char values that are code units of the UTF-16 encoding. For more information on Unicode terminology, refer to the Unicode Glossary.

public static boolean isTitleCase(char ch)
Determines if the specified character is a titlecase character.

A character is a titlecase character if its general category type, provided by Character.getType(ch), is TITLECASE_LETTER.

Some characters look like pairs of Latin letters. For example, there is an uppercase letter that looks like "LJ" and has a corresponding lowercase letter that looks like "lj". A third form, which looks like "Lj", is the appropriate form to use when rendering a word in lowercase with initial capitals, as for a book title.

These are some of the Unicode characters for which this method returns true:

Many other Unicode characters are titlecase too.

Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the isTitleCase(int) sample code for java.lang.Character.isTitleCase(int) definition code for java.lang.Character.isTitleCase(int) method.

Parameters:
ch - the character to be tested.
Returns:
true if the character is titlecase; false otherwise.

Parameters:
codePoint - the character (Unicode code point) for which the directionality property * is requested.
Returns:
the directionality property of the character.

isMirrored sample code for java.lang.Character.isMirrored(char) definition code for java.lang.Character.isMirrored(char)

public static boolean isMirrored(char ch)
Determines whether the character is mirrored according to the Unicode specification. Mirrored characters should have their glyphs horizontally mirrored when displayed in text that is right-to-left. For example, '\u0028' LEFT PARENTHESIS is semantically defined to be an opening parenthesis. This will appear as a "(" in text that is left-to-right but as a ")" in text that is right-to-left.

Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the isMirrored(int) sample code for java.lang.Character.isMirrored(int) definition code for java.lang.Character.isMirrored(int) method.

Parameters:
ch - char for which the mirrored property is requested
Returns:
true if the char is mirrored, false if the char is not mirrored or is not defined.
Since:
1.4

isMirrored sample code for java.lang.Character.isMirrored(int) definition code for java.lang.Character.isMirrored(int)

public static boolean isMirrored(int codePoint)
Determines whether the specified character (Unicode code point) is mirrored according to the Unicode specification. Mirrored characters should have their glyphs horizontally mirrored when displayed in text that is right-to-left. For example, '\u0028' LEFT PARENTHESIS is semantically defined to be an opening parenthesis. This will appear as a "(" in text that is left-to-right but as a ")" in text that is right-to-left.

Parameters:
codePoint - the character (Unicode code point) to be tested.
Returns:
true if the character is mirrored, false if the character is not mirrored or is not defined.
Since:
1.5

compareTo sample code for java.lang.Character.compareTo(java.lang.Character) definition code for java.lang.Character.compareTo(java.lang.Character)

public int compareTo(Character sample code for java.lang.Character definition code for java.lang.Character  anotherCharacter)
Compares two Character objects numerically.

Specified by:
compareTo sample code for java.lang.Comparable.compareTo(T) definition code for java.lang.Comparable.compareTo(T) in interface Comparable sample code for java.lang.Comparable definition code for java.lang.Comparable <Character sample code for java.lang.Character definition code for java.lang.Character >
Parameters:
anotherCharacter - the Character to be compared.
Returns:
the value 0 if the argument Character is equal to this Character; a value less than 0 if this Character is numerically less than the Character argument; and a value greater than 0 if this Character is numerically greater than the Character argument (unsigned comparison). Note that this is strictly a numerical comparison; it is not locale-dependent.
Since:
1.2

reverseBytes sample code for java.lang.Character.reverseBytes(char) definition code for java.lang.Character.reverseBytes(char)

public static char reverseBytes(char ch)
Returns the value obtained by reversing the order of the bytes in the specified char value.

Returns:
the value obtained by reversing (or, equivalently, swapping) the bytes in the specified char value.
Since:
