Constructor Detail

Short

public Short(String string)
      throws NumberFormatException

Constructs a new instance of this class given a string.

Parameters:

string - a string representation of a short quantity.

Throws:

NumberFormatException - if the argument could not be parsed as a short quantity.

Short

public Short(short value)

Constructs a new instance of the receiver which represents the short valued argument.

Parameters:

value - the short to store in the new instance.

Method Detail

byteValue

public byte byteValue()

Returns the byte value which the receiver represents

Overrides:

byteValue in class Number

Returns:

byte the value of the receiver.

compareTo

public int compareTo(Short object)

Compares this Short to the Short passed. If this instance's value is equal to the value of the instance passed, then 0 is returned. If this instance's value is less than the value of the instance passed, then a negative value is returned. If this instance's value is greater than the value of the instance passed, then a positive value is returned.

Specified by:

compareTo in interface Comparable<Short>

Parameters:

object - The instance to compare to.

Returns:

int which should be <0 if the receiver should sort before the argument, 0 if the receiver should sort in the same position as the argument, and >0 if the receiver should sort after the argument.

Throws:

NullPointerException - if object is null.

Since:

1.2

decode

public static Short decode(String string)
                    throws NumberFormatException

Parses the string argument as if it was a short value and returns the result. Throws NumberFormatException if the string does not represent an int quantity. The string may be a hexadecimal ("0x..."), octal ("0..."), or decimal ("...") representation of a byte.

Parameters:

string - a string representation of a short quantity.

Returns:

Short the value represented by the argument

Throws:

NumberFormatException - if the argument could not be parsed as a short quantity.

doubleValue

public double doubleValue()

Returns the double value which the receiver represents

Specified by:

doubleValue in class Number

Returns:

double the value of the receiver.

equals

public boolean equals(Object object)

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison.

In this case, the argument must also be a Short, and the receiver and argument must represent the same short value.

Overrides:

equals in class Object

Parameters:

object - the object to compare with this object

Returns:

true if the object is the same as this object false if it is different from this object

See Also:

hashCode()

floatValue

public float floatValue()

Returns the float value which the receiver represents

Specified by:

floatValue in class Number

Returns:

float the value of the receiver.

hashCode

public int hashCode()

Returns an integer hash code for the receiver. Any two objects which answer true when passed to equals must answer the same value for this method.

Overrides:

hashCode in class Object

Returns:

the receiver's hash

See Also:

equals(java.lang.Object)

intValue

public int intValue()

Returns the int value which the receiver represents

Specified by:

intValue in class Number

Returns:

int the value of the receiver.

longValue

public long longValue()

Returns the long value which the receiver represents

Specified by:

longValue in class Number

Returns:

long the value of the receiver.

parseShort

public static short parseShort(String string)
                        throws NumberFormatException

Parses the string argument as if it was a short value and returns the result. Throws NumberFormatException if the string does not represent an short quantity.

                        throws NumberFormatException

Parses the string argument as if it was a short value and returns the result. Throws NumberFormatException if the string does not represent a single short quantity. The second argument specifies the radix to use when parsing the value.

Parameters:

string - a string representation of a short quantity.

Returns the short value which the receiver represents

Overrides:

shortValue in class Number

Returns:

short the value of the receiver.

toString

public String toString()

Returns a string containing a concise, human-readable description of the receiver.

Overrides:

toString in class Object

a printable representation for the receiver.

toString

public static String toString(short value)

Returns a string containing a concise, human-readable description of the argument.

Parameters:

value - short the short to convert.

String a printable representation for the short.

valueOf

public static Short valueOf(String string)
                     throws NumberFormatException

Parses the string argument as if it was a short value and returns a Short representing the result. Throws NumberFormatException if the string does not represent a single short quantity.

Parameters:

string - a string representation of a short quantity.

Returns:

Short the value represented by the argument

Throws:

NumberFormatException - if the argument could not be parsed as a short quantity.

valueOf

public static Short valueOf(String string,
                            int radix)
                     throws NumberFormatException

Parses the string argument as if it was a short value and returns a Short representing the result. Throws NumberFormatException if the string does not represent a short quantity. The second argument specifies the radix to use when parsing the value.

Parameters:

string - a string representation of a short quantity.

The reversed value.

Since:

1.5

valueOf

public static Short valueOf(short s)

Returns a Short instance for the short value passed. This method is preferred over the constructor, as this method may maintain a cache of instances.
