public final class Short extends Number implements Comparable<Short>
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.

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:
null or is a string of
length zero.
Character.MIN_RADIX or larger than Character.MAX_RADIX.

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.s - a String containing the short

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))
s - the string to be parsedradix - the radix to be used in interpreting sShort object holding the value

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:

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.s - a short value.Short instance representing s.public static Short decode(String nm) throws NumberFormatException
String into a Short.
Accepts decimal, hexadecimal, and octal numbers given by
the following grammar:
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.

int by an unsigned
conversion. In an unsigned conversion to an int, the
high-order 16 bits of the int 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 int value and negative short values are mapped to an int value equal to the
input plus 216.x - the value to convert to an unsigned intint by an unsigned
conversionpublic static long toUnsignedLong(short x)
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.x - the value to convert to an unsigned longlong by an unsigned
