/**
|
|
|
32 |
* The <code>Character</code> class wraps a value of the primitive
|
|
|
33 |
* type <code>char</code> in an object. An object of type
|
|
|
34 |
* <code>Character</code> contains a single field whose type is
|
|
|
35 |
* <code>char</code>.
|
|
|
36 |
* <p>
|
|
|
37 |
* In addition, this class provides several methods for determining
|
|
|
38 |
* a character's category (lowercase letter, digit, etc.) and for converting
|
|
|
39 |
* characters from uppercase to lowercase and vice versa.
|
|
|
40 |
* <p>
|
|
|
41 |
* Character information is based on the Unicode Standard, version 4.0.
|
|
|
42 |
* <p>
|
|
|
43 |
* The methods and data of class <code>Character</code> are defined by
|
|
|
44 |
* the information in the <i>UnicodeData</i> file that is part of the
|
|
|
45 |
* Unicode Character Database maintained by the Unicode
|
|
|
46 |
* Consortium. This file specifies various properties including name
|
|
|
47 |
* and general category for every defined Unicode code point or
|
|
|
48 |
* character range.
|
|
|
49 |
* <p>
|
|
|
50 |
* The file and its description are available from the Unicode Consortium at:
|

* <h4><a name="unicode">Unicode Character Representations</a></h4>
|
|
|
56 |
*
|
|
|
57 |
* <p>The <code>char</code> data type (and therefore the value that a
|
|
|
58 |
* <code>Character</code> object encapsulates) are based on the
|
|
|
59 |
* original Unicode specification, which defined characters as
|
|
|
60 |
* fixed-width 16-bit entities. The Unicode standard has since been
|
|
|
61 |
* changed to allow for characters whose representation requires more
|
|
|
62 |
* than 16 bits. The range of legal <em>code point</em>s is now
|
|
|
63 |
* U+0000 to U+10FFFF, known as <em>Unicode scalar value</em>.
|
|
|
64 |
* (Refer to the <a
|
|
|
65 |
* href="http://www.unicode.org/reports/tr27/#notation"><i>
|
|
|
66 |
* definition</i></a> of the U+<i>n</i> notation in the Unicode
|
|
|
67 |
* standard.)
|
|
|
68 |
*
|
|
|
69 |
* <p>The set of characters from U+0000 to U+FFFF is sometimes
|
|
|
70 |
* referred to as the <em>Basic Multilingual Plane (BMP)</em>. <a
|
|
|
71 |
* name="supplementary">Characters</a> whose code points are greater
|
|
|
72 |
* than U+FFFF are called <em>supplementary character</em>s. The Java
|
|
|
73 |
* 2 platform uses the UTF-16 representation in <code>char</code>
|
|
|
74 |
* arrays and in the <code>String</code> and <code>StringBuffer</code>
|
|
|
75 |
* classes. In this representation, supplementary characters are
|
|
|
76 |
* represented as a pair of <code>char</code> values, the first from
|
|
|
77 |
* the <em>high-surrogates</em> range, (\uD800-\uDBFF), the
|
|
|
78 |
* second from the <em>low-surrogates</em> range
|
|
|
79 |
* (\uDC00-\uDFFF).
|
|
|
80 |
*
|
|
|
81 |
* <p>A <code>char</code> value, therefore, represents Basic
|
|
|
82 |
* Multilingual Plane (BMP) code points, including the surrogate
|
|
|
83 |
* code points, or code units of the UTF-16 encoding. An
|
|
|
84 |
* <code>int</code> value represents all Unicode code points,
|
|
|
85 |
* including supplementary code points. The lower (least significant)
|
|
|
86 |
* 21 bits of <code>int</code> are used to represent Unicode code
|
|
|
87 |
* points and the upper (most significant) 11 bits must be zero.
|
|
|
88 |
* Unless otherwise specified, the behavior with respect to
|
|
|
89 |
* supplementary characters and surrogate <code>char</code> values is
|
|
|
90 |
* as follows:
|
|
|
91 |
*
|
|
|
92 |
* <ul>
|
|
|
93 |
* <li>The methods that only accept a <code>char</code> value cannot support
|
|
|
94 |
* supplementary characters. They treat <code>char</code> values from the
|
|
|
95 |
* surrogate ranges as undefined characters. For example,
|
|
|
96 |
* <code>Character.isLetter('\uD840')</code> returns <code>false</code>, even though
|
|
|
97 |
* this specific value if followed by any low-surrogate value in a string
|
|
|
98 |
* would represent a letter.
|
|
|
99 |
*
|
|
|
100 |
* <li>The methods that accept an <code>int</code> value support all
|
|
|
101 |
* Unicode characters, including supplementary characters. For
|
|
|
102 |
* example, <code>Character.isLetter(0x2F81A)</code> returns
|
|
|
103 |
* <code>true</code> because the code point value represents a letter
|
|
|
104 |
* (a CJK ideograph).
|
|
|
105 |
* </ul>
|
|
|
106 |
*
|
|
|
107 |
* <p>In the Java SE API documentation, <em>Unicode code point</em> is
|
|
|
108 |
* used for character values in the range between U+0000 and U+10FFFF,
|
|
|
109 |
* and <em>Unicode code unit</em> is used for 16-bit
|
|
|
110 |
* <code>char</code> values that are code units of the <em>UTF-16</em>
|
|
|
111 |
* encoding. For more information on Unicode terminology, refer to the

2019 |
* <ol>
|
|
|
2020 |
* <li> Canonical block names as defined by the Unicode Standard.
|
|
|
2021 |
* For example, the standard defines a "Basic Latin" block. Therefore, this
|
|
|
2022 |
* method accepts "Basic Latin" as a valid block name. The documentation of
|
|
|
2023 |
* each UnicodeBlock provides the canonical name.
|
|
|
2024 |
* <li>Canonical block names with all spaces removed. For example, "BasicLatin"
|
|
|
2025 |
* is a valid block name for the "Basic Latin" block.
|
|
|
2026 |
* <li>The text representation of each constant UnicodeBlock identifier.
|
|
|
2027 |
* For example, this method will return the {@link #BASIC_LATIN} block if
|
|
|
2028 |
* provided with the "BASIC_LATIN" name. This form replaces all spaces and
|
|
|
2029 |
* hyphens in the canonical name with underscores.
|
|
|
2030 |
* </ol>
|
|
|
2031 |
* Finally, character case is ignored for all of the valid block name forms.
|
|
|
2032 |
* For example, "BASIC_LATIN" and "basic_latin" are both valid block names.
|
|
|
2033 |
* The en_US locale's case mapping rules are used to provide case-insensitive
|
|
|
2034 |
* string comparisons for block name validation.
|
|
|
2035 |
* <p>
