All Implemented Interfaces:

Serializable, Comparable<Short>
```
public final class Short
extends Number
implements Comparable<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.

Since:

JDK1.1

    Parameters:
    
    s - the short to be converted
    
    Returns:

                               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 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 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') 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.
  - parseShort
```
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 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.
  - valueOf
```
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 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.
  - valueOf
```
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 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.
  - valueOf
```
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.

  - decode
```
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:
    Sign_opt DecimalNumeral
    Sign_opt 0x HexDigits
    Sign_opt 0X HexDigits
    Sign_opt # HexDigits
    Sign_opt 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.

Consequently, zero and positive short values are mapped to a numerically equal int value and negative short values are mapped to an int value equal to the input plus 2¹⁶.
    
    Parameters:
    
    x - the value to convert to an unsigned int
    
    Returns:

```
public static long toUnsignedLong(short x)
```
    Converts the argument to a long by an unsigned conversion. In an unsigned conversion to a long, the high-order 48 bits of the long are zero and the low-order 16 bits are equal to the bits of the short argument. Consequently, zero and positive short values are mapped to a numerically equal long value and negative short values are mapped to a long value equal to the input plus 2¹⁶.
    
    Parameters:
    
    x - the value to convert to an unsigned long
    
    Returns:
    
    the argument converted to long by an unsigned conversion
    
    Since:
    
    1.8
