public final class Short extends Number implements Comparable<Short>
Short
class wraps a value of primitive type short
in an object. An object of type Short
contains a
single field whose type is short
.
In addition, this class provides several methods for converting
a short
to a String
and a String
to a
short
, as well as other constants and methods useful when
dealing with a short
.

the following grammar:

The sequence of characters following an optional
sign and/or radix specifier ("0x

"#
", or leading zero) is parsed as by the Short.parseShort
method with the indicated radix (10, 16, or
8). This sequence of characters must represent a positive
value or a NumberFormatException
will be thrown. The
result is negated if first character of the specified String
is the minus sign. No whitespace characters are
permitted in the String
.

should generally be used in preference to the constructor

significantly better space and time performance by caching

is interpreted as representing a signed decimal
short

the parseShort(java.lang.String)
method. The result is
a Short
object that represents the
short
