    Returns:

    the primitive float value of this object.

  • hashCode

    public int hashCode()

    Description copied from class: Object
    Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

    Note that hash values must not change over time unless information used in equals comparisons also changes.

    See Writing a correct hashCode method if you intend implementing your own hashCode method.

    Overrides:

    hashCode in class Object

    Returns:

    this object's hash code.

    See Also:

    Object.equals(java.lang.Object)

  • intValue

    public int intValue()

    Description copied from class: Number
    Returns this object's value as an int. Might involve rounding and/or truncating the value, so it fits into an int.

    Specified by:

    intValue in class Number

    Returns:

    the primitive int value of this object.

  • longValue

    public long longValue()

    Description copied from class: Number
    Returns this object's value as a long. Might involve rounding and/or truncating the value, so it fits into a long.

    Specified by:

    longValue in class Number

    Returns:

    the primitive long value of this object.

  • parseShort

    public static short parseShort(String string)
                            throws NumberFormatException

    Parses the specified string as a signed decimal short value. The ASCII character - ('-') is recognized as the minus sign.

    Parameters:

    string - the string representation of a short value.

    Returns:

    the primitive short value represented by string.

    Throws:

    NumberFormatException - if string cannot be parsed as a short value.

                   int radix)
                            throws NumberFormatException

    Parses the specified string as a signed short value using the specified radix. The ASCII character - ('-') is recognized as the minus sign.

    Parameters:

    string - the string representation of a short value.

    radix - the radix to use when parsing.

    Returns:

    the primitive short value represented by string using radix.

    Throws:

    this object's primitive value.

  • toString

    public String toString()

    Description copied from class: Object
    Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

       getClass().getName() + '@' + Integer.toHexString(hashCode())

    See Writing a useful toString method if you intend implementing your own toString method.

    Overrides:

    toString in class Object

    Returns:

    a printable representation of this object.

  • toString

    public static String toString(short value)

    Returns a string containing a concise, human-readable description of the specified short value with radix 10.

    Parameters:

    value - the short to convert to a string.

    Parameters:

    string - the string representation of a short value.

    Returns:

    a Short instance containing the short value represented by string.

    Throws:

    NumberFormatException - if string cannot be parsed as a short value.

    See Also:

    parseShort(String)

  • valueOf

    public static Short valueOf(String string,
                int radix)
                         throws NumberFormatException

    Parses the specified string as a signed short value using the specified radix.

    Parameters:

    string - the string representation of a short value.

    radix - the radix to use when parsing.

    Returns:

    a Short instance containing the short value represented by string using radix.

    Throws:

    NumberFormatException - if string cannot be parsed as a short value, or radix < Character.MIN_RADIX || radix > Character.MAX_RADIX.

    See Also:

    parseShort(String, int)

  • reverseBytes

    public static short reverseBytes(short s)

    Reverses the bytes of the specified short.

    Parameters:

    s - the short value for which to reverse bytes.

    Returns:

    the reversed value.

    Since:

    1.5

  • valueOf

    public static Short valueOf(short s)

    Returns a Short instance for the specified short value.

    If it is not necessary to get a new Short instance, it is recommended to use this method instead of the constructor, since it maintains a cache of instances which may result in better performance.

    Parameters:

    s - the short value to store in the instance.

    Returns:

    a Short instance containing s.
