java.lang.Short
| Short | | final public class Short extends Number implements Comparable<Short>(Code) | | 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 .

DecimalNumeral, HexDigits, and OctalDigits
are defined in §3.10.1
of the Java
Language Specification.
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. a Short object holding the short value represented by nm
throws:
NumberFormatException - if the String does notcontain a parsable short .

| doubleValue | | public double doubleValue()(Code) | | Returns the value of this
Short as a
double .
|
| equals | | public boolean equals(Object obj)(Code) | | Compares this object to the specified object. The result is
true if and only if the argument is not
null and is a
Short object that
contains the same
short value as this object.
Parameters:
obj - the object to compare with true if the objects are the same; false otherwise. |
| floatValue | | public float floatValue()(Code) | | Returns the value of this
Short as a
float .
|
| hashCode | | public int hashCode()(Code) | | Returns a hash code for this
Short .
|
| intValue | | public int intValue()(Code) | | Returns the value of this
Short as an
int .
|
| longValue | | public long longValue()(Code) | | Returns the value of this
Short as a
long .
|
| parseShort | | public static short parseShort(String s, int radix) throws NumberFormatException(Code) | | 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
java.lang.Character.digit(charint) 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
java.lang.Character.MIN_RADIX or larger than
java.lang.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
Parameters:
radix - the radix to be used while parsing s 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(Code) | | 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
Short.parseShort(java.lang.String,int) method.
Parameters:
s - a String containing the short representation to be parsed the short value represented by the argument in decimal.
throws:
NumberFormatException - If the string does notcontain a parsable short . |
| reverseBytes | | public static short reverseBytes(short i)(Code) | | Returns the value obtained by reversing the order of the bytes in the
two's complement representation of the specified
short value.
the value obtained by reversing (or, equivalently, swapping)the bytes in the specified short value.

| shortValue | | public short shortValue()(Code) | | Returns the value of this
Short as a
short .
|
| toString | | public static String toString(short s)(Code) | | Returns a new
String object representing the
specified
short . The radix is assumed to be 10.
Parameters:
s - the short to be converted the string representation of the specified short
See Also: java.lang.Integer.toString(int) |
| toString | | public String toString()(Code) | | Returns a
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
java.lang.Short.toString(short) method.
a string representation of the value of this object inbase 10. |
| valueOf | | public static Short valueOf(String s, int radix) throws NumberFormatException(Code) | | 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
Short.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
Parameters:
radix - the radix to be used in interpreting s a Short object holding the value represented by the string argument in the specified radix.
throws:
NumberFormatException - If the String doesnot contain a parsable short . |
| valueOf | | public static Short valueOf(String s) throws NumberFormatException(Code) | | 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
Short.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 a Short object holding the valuerepresented by the string argument
throws:
NumberFormatException - If the String doesnot contain a parsable short . |
| valueOf | | public static Short valueOf(short s)(Code) | | 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(short) , as this method is likely to yield
significantly better space and time performance by caching
frequently requested values.
Parameters:
s - a short value. a Short instance representing s .
