The Character
class wraps a value of the primitive type char
in an object. An object of class Character
contains a single field whose type is char
.
In addition, this class provides a large number of static methods for
determining a character's category (lowercase letter, digit, etc.)
and for converting characters from uppercase to lowercase and vice
versa.
Unicode Conformance
The fields and methods of class Character
are defined in terms of character information from the Unicode Standard, specifically the UnicodeData file that is part of the Unicode Character Database.
This file specifies properties including name and category for every
assigned Unicode code point or character range. The file is available
from the Unicode Consortium at
http://www.unicode.org.
The Java SE 8 Platform uses character information from version 6.2 of the Unicode Standard, with two extensions. First, the Java SE 8 Platform allows an implementation of class Character
to use the Japanese Era code point, U+32FF
, from the first version of the Unicode Standard after 6.2 that assigns the code point. Second, in recognition of the fact that new currencies appear frequently, the Java SE 8 Platform allows an implementation of class Character
to use the Currency Symbols block from version 10.0 of the Unicode Standard. Consequently, the behavior of fields and methods of class Character
may vary across implementations of the Java SE 8 Platform when processing the aforementioned code points ( outside of version 6.2 ), except for the following methods that define Java identifiers: isJavaIdentifierStart(int)
, isJavaIdentifierStart(char)
, isJavaIdentifierPart(int)
, and isJavaIdentifierPart(char)
. Code points in Java identifiers must be drawn from version 6.2 of the Unicode Standard.
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 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:
- The methods that only accept a
char
value cannot support supplementary characters. They treat char
values from the surrogate ranges as undefined characters. For example, Character.isLetter('\u005CuD840')
returns false
, even though this specific value if followed by any low-surrogate value in a string would represent a letter. - The methods that accept an
int
value support all Unicode characters, including supplementary characters. For example, Character.isLetter(0x2F81A)
returns true
because the code point value represents a letter (a CJK ideograph).
In the Java SE 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.

Returns the UnicodeBlock with the given name. Block names are determined by The Unicode Standard. The file Blocks-<version>.txt defines blocks for a particular version of the standard. The Character
class specifies the version of the standard that it supports.
This method accepts block names in the following forms:
- Canonical block names as defined by the Unicode Standard.
For example, the standard defines a "Basic Latin" block. Therefore, this
method accepts "Basic Latin" as a valid block name. The documentation of
each UnicodeBlock provides the canonical name.
- Canonical block names with all spaces removed. For example, "BasicLatin"
is a valid block name for the "Basic Latin" block.
- The text representation of each constant UnicodeBlock identifier. For example, this method will return the
BASIC_LATIN
block if provided with the "BASIC_LATIN" name. This form replaces all spaces and hyphens in the canonical name with underscores.
Finally, character case is ignored for all of the valid block name forms.
For example, "BASIC_LATIN" and "basic_latin" are both valid block names.
The en_US locale's case mapping rules are used to provide case-insensitive
string comparisons for block name validation.
If the Unicode Standard changes block names, both the previous and
current names will be accepted.
Params: - blockName – A
UnicodeBlock
name.
Throws: - IllegalArgumentException – if
blockName
is an invalid name - NullPointerException – if
blockName
is null

Determines the character representation for a specific digit in the specified radix. If the value of radix
is not a valid radix, or the value of digit
is not a valid digit in the specified radix, the null character ('\u005Cu0000'

argument is valid if it is greater than or equal to MIN_RADIX

is returned.
