The 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
.

A constant holding the maximum value a short
can
have, 215-1.
A constant holding the minimum value a short
can
have, -215.
The number of bits used to represent a short
value in two's
complement binary form.
Constructs a newly allocated Short
object that
represents the specified short
value.
value | the value to be represented by the
Short .
|
---|
Constructs a newly allocated Short
object that
represents the short
value indicated by the
String
parameter. The string is converted to a
short
value in exactly the manner used by the
parseShort
method for radix 10.
s | the String to be converted to a
Short |
---|
NumberFormatException | If the String
does not contain a parsable short . |
---|
Returns the value of this Short
as a
byte

0
if this Short
is
equal to the argument Short
; a value less than
0
if this Short
is numerically less
than the argument Short
; and a value greater than
0
if this Short
is numerically
greater than the argument Short

comparison).Decodes a String
into a Short
.
Accepts decimal, hexadecimal, and octal numbers given by
the following grammar:
DecimalNumeral, HexDigits, and OctalDigits are defined in §3.10.1 of the Java Language Specification.

- Sign:

The sequence of characters following an (optional) negative
sign and/or radix specifier ("0x
", "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
.
nm | the String to decode. |

value represented by nm

Compares this object to the specified object. The result is
true
if and only if the argument is not
null
and is a Short
object that
contains the same short
value as this object.

if the objects are the same;

Parses the string argument as a signed short
in the
radix specified by the second argument. The characters in the
string must all be digits, of the specified radix (as
determined by whether digit(char, int)
returns a nonnegative value) except that the first
character may be an ASCII minus sign '-'
('\u002D'
) to indicate a negative value. The
resulting short
value is returned.
An exception of type NumberFormatException
is
thrown if any of the following situations occurs:
null
or is a string of
length zero.
MIN_RADIX
or larger than MAX_RADIX
.
'-'

string is longer than length 1.

Parses the string argument as a signed decimal short
. 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. 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.
s | a String containing the short
representation to be parsed |
---|

argument in decimal.NumberFormatException | If the string does not

value.

short
Returns a String
object representing this
Short
's value. The value is converted to signed
decimal representation and returned as a string, exactly as if
the short
value were given as an argument to the
toString(short)
method.
Returns a Short
object holding the
value given by the specified String
. The 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:
new Short(Short.parseShort(s))
s | the string to be parsed |

|
---|
Returns a Short
object holding the value
extracted from the specified String
when parsed
with the radix given by the second argument. The first argument
is interpreted as representing a signed short
in
the radix specified by the second argument, exactly as if the
argument were given to the parseShort(java.lang.String, int)
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:
new Short(Short.parseShort(s, radix))
s | the string to be parsed |
---|---|
radix | the radix to be used in interpreting s |
Short
object holding the value
represented by the string argument in the
specified radix.NumberFormatException | If the String does
not contain a parsable short .
|
---|
Returns a 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.
s | a short value. |
