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 object that represents the specified short
value.value - the value to be represented by the Short.public Short(String s) throws NumberFormatException
Short object that represents the short value
indicated by the String parameter. The string is converted to a short value in
exactly the manner used by the parseShort method for radix 10.
Null Analysis restriction: the parameter s is @NonNull,
to ensure that NumberFormatException is thrown only when the string
characters do not represent a valid number. This aligns with the behavior of
Float.parseFloat(String) and Double.parseDouble(String).

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.

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.
Null Analysis restriction: the parameter s is @NonNull,
to ensure that NumberFormatException is thrown only when the string
characters do not represent a valid number. This aligns with the behavior of
Float.parseFloat(String) and Double.parseDouble(String).

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.
'-' ('\u002D') or plus sign '+'

Short as a short.shortValue in class Numbershort.public String toString()
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 toString(short) method.public static String toString(short s)

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 valueOf(String s) throws NumberFormatException
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))
Null Analysis restriction: the parameter s is @NonNull,
to ensure that NumberFormatException is thrown only when the string
characters do not represent a valid number. This aligns with the behavior of
Float.parseFloat(String) and Double.parseDouble(String).

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))
