Class: java.lang.Short

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.

    Parameters:
    @param s the String to be converted to a Short
    Exceptions:
    @exception NumberFormatException If the String does not contain a parsable short.

    Parameters:
    @param anotherShort the Short to be compared.
    Return:

  • decodetop

    public static Short decode(String nm) throws NumberFormatException
    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 defined in §3.10.1 of the Java Language Specification.

    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.

    Parameters:
    @param nm the String to decode.
    Return:
    @return a Short object holding the short value represented by nm
    Exceptions:
    @exception NumberFormatException if the String does not contain a parsable short.

  • parseShorttop

    public static short parseShort(String s) throws NumberFormatException
    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 Short.parseShort(java.lang.String, int) method.
    Parameters:
    @param s a String containing the short representation to be parsed
    Return:
    @return the short value represented by the argument in decimal.
    Exceptions:
    @exception NumberFormatException If the string does not contain a parsable short.

  • parseShorttop

    public static short parseShort(String s, int radix) throws NumberFormatException
    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 Character.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 byte 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 than Character.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') provided that the string is longer than length 1.
    • The value represented by the string is not a value of type short.
    Parameters:
    @param s the String containing the short representation to be parsed
    @param radix the radix to be used while parsing s
    Return:
    @return the short represented by the string argument in the specified radix.
    Exceptions:
    @exception NumberFormatException If the String does not contain a parsable short.

  • reverseBytestop

    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.
    Return:
    @return the value obtained by reversing (or, equivalently, swapping) the bytes in the specified short value.

  • toStringtop

    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 Short.toString(short) method.
    Return:
    @return a string representation of the value of this object in base 10.

  • toStringtop

    public static String toString(short s)
    Returns a new String object representing the specified short. The radix is assumed to be 10.
    Parameters:
    @param s the short to be converted
    Return:
    @return the string representation of the specified short

  • valueOftop

    public static Short valueOf(String s) throws NumberFormatException
    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 Short.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 Byte object equal to the value of:

    new Short(Short.parseShort(s))
    Parameters:
    @param s the string to be parsed
    Return:
    @return a Short object holding the value represented by the string argument
    Exceptions:
    @exception NumberFormatException If the String does not contain a parsable short.

  • valueOftop

    public static Short valueOf(String s, int radix) throws NumberFormatException
    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 Short.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:
    @param s the string to be parsed
    @param radix the radix to be used in interpreting s
    Return:
    @return a Short object holding the value represented by the string argument in the specified radix.
    Exceptions:
    @exception NumberFormatException If the String does not contain a parsable short.

  • valueOftop

    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(short), as this method is likely to yield significantly better space and time performance by caching frequently requested values.
    Parameters:
    @param s a short value.
    Return:
    @return a Short instance representing s.
