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
.

Short

value in
exactly the manner used by the parseShort
method for radix 10.

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

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
.

. The characters in the string must
all be decimal digits, except that the first character may be an ASCII minus sign '-'
('\u002D'
) to indicate a negative value or an ASCII plus sign '+'
('\u002B'
) to indicate a positive value. The resulting short
value is
returned, exactly as if the argument and the radix 10 were given as arguments to the
parseShort(java.lang.String, int)
method.

is thrown only when the string
characters do not represent a valid number. This aligns with the behavior of

the first character may be an ASCII minus sign '-'
( '\u002D'

indicate a negative value or an ASCII plus sign '+'

Short
instance representing the specified short
value. If a new
Short
instance is not required, this method should generally be used in preference to the
constructor Short(short)
, as this method is likely to yield significantly better space
and time performance by caching frequently requested values.
This method will always cache values in the range -128 to 127, inclusive, and may cache other
values outside of this range.s

argument is interpreted as representing a signed decimal short
, exactly as if the
argument were given to the parseShort(java.lang.String)
method. The result is a
Short
object that represents the short
value specified by the string.
In other words, this method returns a Short
object equal to the value of:

the argument were given to the parseShort(java.lang.String, int)
