<summary>This class contains various methods for manipulating arrays (such as

<remarks>
<para>This class contains various methods for manipulating arrays (such as
sorting and searching). This class also contains a static factory
that allows arrays to be viewed as lists.</para>
<para>The methods in this class all throw a <c>NullPointerException</c>,
if the specified array reference is null, except where noted.</para>
<para>The documentation for the methods contained in this class includes
brief descriptions of the <i>implementations</i>. Such descriptions should
be regarded as <i>implementation notes</i>, rather than parts of the
<i>specification</i>. Implementors should feel free to substitute other
algorithms, so long as the specification itself is adhered to. (For
example, the algorithm used by <c>sort(Object[])</c> does not have to be
a MergeSort, but it does have to be <i>stable</i>.)</para>

<returns>index of the search key, if it is contained in the array
within the specified range;
otherwise, <c>(-(<i>insertion point</i>) - 1)</c>. The
<i>insertion point</i> is defined as the point at which the
key would be inserted into the array: the index of the first

<remarks>
<para>Searches a range of
the specified array for the specified object using the binary
search algorithm.
The range must be sorted into ascending order
according to the
Comparable natural ordering
of its elements (as by the
<c>#sort(Object[], int, int)</c> method) prior to making this
call. If it is not sorted, the results are undefined.
(If the range contains elements that are not mutually comparable (for
example, strings and integers), it <i>cannot</i> be sorted according
to the natural ordering of its elements, hence results are undefined.)
If the range contains multiple
elements equal to the specified object, there is no guarantee which
one will be found.</para>
