and aString
to ashort
, as well as other constants and methods useful when dealing with ashort
. Since:

Constructor Detail

Short
@Deprecated(since="9") public Short(short value)
Deprecated. It is rarely appropriate to use this constructor. The static factoryvalueOf(short)
is generally a better choice, as it is likely to yield significantly better space and time performance.Constructs a newly allocatedShort
object that represents the specifiedshort
value. Parameters:
value
 the value to be represented by theShort
.

Short
@Deprecated(since="9") public Short(String s) throws NumberFormatException
Deprecated. It is rarely appropriate to use this constructor. UseparseShort(String)
to convert a string to ashort
primitive, or usevalueOf(String)
to convert a string to aShort
object.Constructs a newly allocatedShort
object that represents theshort
value indicated by theString
parameter. The string is converted to ashort
value in exactly the manner used by theparseShort
method for radix 10. Parameters:
s
 theString
to be converted to aShort
 Throws:
NumberFormatException
 If theString
does not contain a parsableshort
.

public static String toString(short s)
Returns a newString
object representing the specifiedshort
. The radix is assumed to be 10. Parameters:

short
 See Also:
Integer.toString(int)

parseShort
public static short parseShort(String s, int radix) throws NumberFormatException
Parses the string argument as a signedshort
in the radix specified by the second argument. The characters in the string must all be digits, of the specified radix (as determined by whetherCharacter.digit(char, int)
returns a nonnegative value) 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 resultingshort
value is returned.An exception of type
NumberFormatException
is thrown if any of the following situations occurs: The first argument is
null
or is a string of length zero.  The radix is either smaller than
Character.MIN_RADIX
or larger thanCharacter.MAX_RADIX
.  Any character of the string is not a digit of the
specified radix, except that the first character may be a minus
sign
''
('\u002D'
) or plus sign'+'
('\u002B'
) provided that the string is longer than length 1.  The value represented by the string is not a value of type
short
.
 Parameters:
s
 theString
containing theshort
representation to be parsedradix
 the radix to be used while parsings
 Returns:
 the
short
represented by the string argument in the specified radix.  Throws:
NumberFormatException
 If theString
does not contain a parsableshort
.
 The first argument is

parseShort
public static short parseShort(String s) throws NumberFormatException
Parses the string argument as a signed decimalshort
. 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 resultingshort
value is returned, exactly as if the argument and the radix 10 were given as arguments to theparseShort(java.lang.String, int)
method. Parameters:
s
 aString
containing theshort
representation to be parsed Returns:
 the
short
value represented by the argument in decimal.  Throws:
NumberFormatException
 If the string does not contain a parsableshort
.

valueOf
public static Short valueOf(String s, int radix) throws NumberFormatException
Returns aShort
object holding the value extracted from the specifiedString
when parsed with the radix given by the second argument. The first argument is interpreted as representing a signedshort
in the radix specified by the second argument, exactly as if the argument were given to theparseShort(java.lang.String, int)
method. The result is aShort
object that represents theshort
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))
 Parameters:
s
 the string to be parsedradix
 the radix to be used in interpretings
 Returns:
 a
Short
object holding the value represented by the string argument in the specified radix.  Throws:
NumberFormatException
 If theString
does not contain a parsableshort
.

valueOf
public static Short valueOf(String s) throws NumberFormatException
Returns aShort
object holding the value given by the specifiedString
. The argument is interpreted as representing a signed decimalshort
, exactly as if the argument were given to theparseShort(java.lang.String)
method. The result is aShort
object that represents theshort
value specified by the string.In other words, this method returns a
Short
object equal to the value of:new Short(Short.parseShort(s))
 Parameters:
s
 the string to be parsed Returns:
 a
Short
object holding the value represented by the string argument  Throws:
NumberFormatException
 If theString
does not contain a parsableshort
.

valueOf
public static Short valueOf(short s)
Returns aShort
instance representing the specifiedshort
value. If a newShort
instance is not required, this method should generally be used in preference to the constructorShort(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. Parameters:
s
 a short value. Returns:
 a
Short
instance representings
.  Since:
 1.5

decode
public static Short decode(String nm) throws NumberFormatException
Decodes aString

 Sign_{opt}
0x
HexDigits  Sign_{opt}
0X
HexDigits  Sign_{opt}
#
HexDigits  Sign_{opt}
0
OctalDigits  Sign:

+
The sequence of characters following an optional sign and/or radix specifier ("
0x
", "0X
", "#
", or leading zero) is parsed as by theShort.parseShort
method with the indicated radix (10, 16, or 8). This sequence of characters must represent a positive value or aNumberFormatException
will be thrown. The result is negated if first character of the specifiedString
is the minus sign. No whitespace characters are permitted in theString
. Parameters:
nm
 theString
to decode. Returns:

values are mapped to a numerically equallong
value and negativeshort
values are mapped to along
