Class Overview

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.

Fields

public static final Class<Short> TYPE

The Class instance representing the primitive type short.

Public Constructors

public Short (short value)

Constructs a newly allocated Short object that represents the specified short value.

Parameters
value the value to be represented by the Short.

public Short (String s)

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.

Parameters
s the String to be converted to a Short
Throws
NumberFormatException If the String does not contain a parsable short.

Public Methods

public byte byteValue ()

Returns the value of this Short as a byte.

public static int compare (short x, short y)

Compares two short values numerically. The value returned is identical to what would be returned by:

    Short.valueOf(x).compareTo(Short.valueOf(y))
 

Parameters
x the first short to compare
y the second short to compare
Returns
  • the value 0 if x == y; a value less than 0 if x < y; and a value greater than 0 if x > y

public int compareTo (Short anotherShort)

Compares two Short objects numerically.

Parameters
anotherShort the Short to be compared.
Returns
  • the value 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 (signed comparison).

public static Short decode (String nm)

Decodes a String into a Short. Accepts decimal, hexadecimal, and octal numbers given by the following grammar:

DecodableString:
Signopt DecimalNumeral
Signopt 0x HexDigits
Signopt 0X HexDigits
Signopt # HexDigits
Signopt 0 OctalDigits

Sign:
-
+
DecimalNumeral, HexDigits, and OctalDigits are as defined in section 3.10.1 of The Java™ Language Specification, except that underscores are not accepted between digits.

The sequence of characters following an optional 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.

Parameters
nm the String to decode.
Returns
  • a Short object holding the short value represented by nm
Throws
NumberFormatException if the String does not contain a parsable short.

public double doubleValue ()

Returns the value of this Short as a double.

public boolean equals (Object obj)

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.

Parameters
obj the object to compare with
Returns
  • true if the objects are the same; false otherwise.

public float floatValue ()

Returns the value of this Short as a float.

public static int hashCode (short value)

Returns a hash code for a short value; compatible with Short.hashCode().

Parameters
value the value to hash
Returns
  • a hash code value for a short value.

public int hashCode ()

Returns a hash code for this Short; equal to the result of invoking intValue().

Returns
  • a hash code value for this Short

public int intValue ()

Returns the value of this Short as an int.

public long longValue ()

Returns the value of this Short as a long.

public static short parseShort (String s)

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 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.

Parameters
s a String containing the short representation to be parsed
Returns
  • the short value represented by the argument in decimal.
Throws
NumberFormatException If the string does not contain a parsable short.

public static short parseShort (String s, int radix)

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 or an ASCII plus sign '+' ('\u002B') to indicate a positive value. The resulting short 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 MIN_RADIX or larger than 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 the String containing the short representation to be parsed
radix the radix to be used while parsing s
Returns
  • the short represented by the string argument in the specified radix.
Throws
NumberFormatException If the String does not contain a parsable short.

public static short reverseBytes (short i)

Returns the value obtained by reversing the order of the bytes in the two's complement representation of the specified short value.

Returns
  • the value obtained by reversing (or, equivalently, swapping) the bytes in the specified short value.

public short shortValue ()

Returns the value of this Short as a short.

public static String toString (short s)

Returns a new String object representing the specified short. The radix is assumed to be 10.

Parameters
s the short to be converted
Returns
  • the string representation of the specified short
See Also

public String toString ()

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 string representation of the value of this object in base 10.

public static Short valueOf (String s)

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))

Parameters
s the string to be parsed
Returns
  • a Short object holding the value represented by the string argument
Throws
NumberFormatException If the String does not contain a parsable short.

public static Short valueOf (short s)

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. 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 representing s.

public static Short valueOf (String s, int radix)

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))

Parameters
s the string to be parsed
radix the radix to be used in interpreting s
Returns
  • a Short object holding the value represented by the string argument in the specified radix.
Throws
NumberFormatException If the String does not contain a parsable short.
