<div class="block">The <code>String</code> class represents character strings. All
|
|
string literals in Java programs, such as <code>"abc"</code>, are
|
|
implemented as instances of this class.
|
|
<p>
|
|
Strings are constant; their values cannot be changed after they
|
|
are created. String buffers support mutable strings.
|
|
Because String objects are immutable they can be shared. For example:
|
|
<p><blockquote><pre>
|
|
String str = "abc";
|
|
</pre></blockquote><p>
|
|
is equivalent to:
|
|
<p><blockquote><pre>
|
|
char data[] = {'a', 'b', 'c'};
|
|
String str = new String(data);
|
|
</pre></blockquote><p>
|
|
Here are some more examples of how strings can be used:
|
|
<p><blockquote><pre>
|
|
System.out.println("abc");
|
|
String cde = "cde";
|
|
System.out.println("abc" + cde);
|
|
String c = "abc".substring(2,3);
|
|
String d = cde.substring(1, 2);
|
|
</pre></blockquote>
|
|
<p>
|
|
The class <code>String</code> includes methods for examining
|
|
individual characters of the sequence, for comparing strings, for
|
|
searching strings, for extracting substrings, and for creating a
|
|
copy of a string with all characters translated to uppercase or to
|
|
lowercase. Case mapping is based on the Unicode Standard version
|
|
specified by the <a href="../../java/lang/Character.html" title="class in java.lang"><code>Character</code></a> class.
|
|
<p>
|
|
The Java language provides special support for the string
|
|
concatenation operator ( + ), and for conversion of
|
|
other objects to strings. String concatenation is implemented
|
|
through the <code>StringBuilder</code>(or <code>StringBuffer</code>)
|
|
class and its <code>append</code> method.
|
|
String conversions are implemented through the method
|
|
<code>toString</code>, defined by <code>Object</code> and
|
|
inherited by all classes in Java. For additional information on
|
|
string concatenation and conversion, see Gosling, Joy, and Steele,
|
|
<i>The Java Language Specification</i>.
|
|
|
|
<p> Unless otherwise noted, passing a <tt>null</tt> argument to a constructor
|
|
or method in this class will cause a <a href="../../java/lang/NullPointerException.html" title="class in java.lang"><code>NullPointerException</code></a> to be
|
|
thrown.
|
|
|
|
<p>A <code>String</code> represents a string in the UTF-16 format
|
|
in which <em>supplementary characters</em> are represented by <em>surrogate
|
|
pairs</em> (see the section <a href="Character.html#unicode">Unicode
|
|
Character Representations</a> in the <code>Character</code> class for
|
|
more information).
|
|
Index values refer to <code>char</code> code units, so a supplementary
|
|
character uses two positions in a <code>String</code>.
|
|
<p>The <code>String</code> class provides methods for dealing with
|
|
Unicode code points (i.e., characters), in addition to those for
|
|
dealing with Unicode code units (i.e., <code>char</code> values).</div>
