MIN_VALUE

 public static final short MIN_VALUE

The minimum value a Short can have.

MAX_VALUE

 public static final short MAX_VALUE

The maximum value a Short can have.

TYPE

 public static final Class TYPE

The Class object representing the primitive type short.

Short

 public Short(short value)

Constructs a Short object initialized to the specified short value.

Parameters:: value - the initial value of the Short

Short

 public Short(String s) throws NumberFormatException

Constructs a Short object initialized to the value specified by the String parameter. The radix is assumed to be 10.

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

toString

 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

parseShort

 public static short parseShort(String s) throws NumberFormatException

Assuming the specified String represents a short, returns that short's value. Throws an exception if the String cannot be parsed as a short. The radix is assumed to be 10.

Parameters:: s - the String containing the short
Throws: NumberFormatException: If the string does not contain a parsable short.

parseShort

 public static short parseShort(String s,
                                int radix) throws NumberFormatException

Assuming the specified String represents a short, returns that short's value. Throws an exception if the String cannot be parsed as a short.

Parameters:: s - the String containing the short; radix - the radix to be used
Throws: NumberFormatException: If the String does not contain a parsable short.

valueOf

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

Assuming the specified String represents a short, returns a new Short object initialized to that value. Throws an exception if the String cannot be parsed as a short.

Parameters:: s - the String containing the integer; radix - the radix to be used
Throws: NumberFormatException: If the String does not contain a parsable short.

valueOf

 public static Short valueOf(String s) throws NumberFormatException

Assuming the specified String represents a short, returns a new Short object initialized to that value. Throws an exception if the String cannot be parsed as a short.

Parameters:: s - the String containing the integer
Throws: NumberFormatException: If the String does not contain a parsable short.

decode
