public final class Short extends Number implements Comparable<Short>
Short
represent primitive
short
values.
Additionally, this class provides various helper functions and variables
related to shorts.Modifier and Type | Field and Description |
---|---|
static short |
MAX_VALUE
The minimum value a
short can represent is 32767 (or
215). |
static short |
MIN_VALUE
The minimum value a
short can represent is -32768 (or
-215). |
static int |
SIZE
The number of bits needed to represent a
short . |
static Class<Short> |
TYPE
The primitive type
short is represented by this
Class object. |
Constructor and Description |
---|
Short(short value)
Create a
Short object representing the value of the
short argument. |

public static short parseShort(String s, int radix)
String
into a short
using the specified radix (base). The string must not be null
or empty. It may begin with an optional '-', which will negate the answer,
provided that there are also valid digits. Each digit is parsed as if by
Character.digit(d, radix)
, and must be in the range
0
to radix - 1
. Finally, the result must be
within MIN_VALUE
to MAX_VALUE
, inclusive.
Unlike Double.parseDouble, you may not have a leading '+'.s

public static Short decode(String s)
String

The String
may represent decimal, hexadecimal, or
octal numbers.
The extended BNF grammar is as follows:
DecodableString: ( [Finally, the value must be in the range-
] DecimalNumber ) | ( [-
] (0x
|0X
|#
) HexDigit { HexDigit } ) | ( [-
]0
{ OctalDigit } ) DecimalNumber: DecimalDigit except '0' { DecimalDigit } DecimalDigit: Character.digit(d, 10) has value 0 to 9 OctalDigit: Character.digit(d, 8) has value 0 to 7 DecimalDigit: Character.digit(d, 16) has value 0 to 15
