All string literals, 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. <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. <p><P><P><DL><DT><B>See Also:</B><DD><A
