Short (Java 2 Platform SE 5.0)

java.lang.Object
  java.lang.Number
      java.lang.Short

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

Number, Serialized Form

public static final short MIN_VALUE

A constant holding the minimum value a short can have, -2¹⁵.

See Also:

Constant Field Values

public static final short MAX_VALUE

A constant holding the maximum value a short can have, 2¹⁵-1.

See Also:

Constant Field Values

public static final Class<Short> TYPE

The Class instance representing the primitive type short.

public static final int SIZE

The number of bits used to represent a short value in two's complement binary form.

Constant Field Values

public Short(short value)

Constructs a newly allocated Short object that represents the specified short value.

Parameters:

value - the value to be represented by the Short.

public Short(String s)
      throws NumberFormatException

Constructs a newly allocated 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.

Parameters:

s - the String to be converted to a Short

Throws:

NumberFormatException - If the String does not contain a parsable short.

See Also:

parseShort(java.lang.String, int)

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

Returns:

the string representation of the specified short

See Also:

Integer.toString(int)

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. 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.

public static short parseShort(String s,
                               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. The resulting byte 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') 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.

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.

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 Byte 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.

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.

Parameters:

s - a short value.

Returns:

a Short instance representing s.

1.5

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 defined in §3.10.1 of the Java Language Specification.

The sequence of characters following an (optional) negative 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.
