Answers a string containing a concise, human-readable description of the
receiver. | | public static String | toString(byte value)
Answers a string containing a concise, human-readable description of the
argument.
Parameters:

Parses the string argument as if it was a byte value and returns a Byte
representing the result. | | public static Byte | valueOf(String string, int radix)
Parses the string argument as if it was a byte value and returns a Byte

| TYPE | | final public static Class<Byte> TYPE(Code) | | The java.lang.Class that represents this class.
|
| Byte | | public Byte(byte value)(Code) | | Constructs a new instance of the receiver which represents the byte
valued argument.
Parameters:
value - the byte to store in the new instance. |
| Byte | | public Byte(String string) throws NumberFormatException(Code) | | Constructs a new instance of this class given a string.
Parameters:
string - a string representation of a single byte quantity.
throws:
NumberFormatException - if the argument could not be parsed as a byte quantity. |
| byteValue | | public byte byteValue()(Code) | | Answers the byte value which the receiver represents
byte the value of the receiver. |
| compareTo | | public int compareTo(Byte object)(Code) | | Compares this Byte to the Byte 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.
Parameters:
object - The instance to compare to.
throws:
NullPointerException - if object is null.

| decode | | public static Byte decode(String string) throws NumberFormatException(Code) | | Parses the string argument as if it was a byte value and returns the
result. It is an error if the received string does not contain a
representation of a single byte quantity. The string may be a hexadecimal
("0x..."), octal ("0..."), or decimal ("...") representation of a byte.
Parameters:
string - a string representation of a single byte quantity. Byte the value represented by the argument
throws:
NumberFormatException - if the argument could not be parsed as a byte quantity. |
| doubleValue | | public double doubleValue()(Code) | | Answers the double value which the receiver represents
double the value of the receiver. |
| equals | | public boolean equals(Object object)(Code) | | Compares the argument to the receiver, and answers true if they represent
the same object using a class specific comparison.
In this case, the argument must also be a Byte, and the receiver and
argument must represent the same byte value.
Parameters:
object - the object to compare with this object true if the object is the same as this objectfalse if it is different from this object
See Also: Byte.hashCode |
| floatValue | | public float floatValue()(Code) | | Answers the float value which the receiver represents
float the value of the receiver. |
| hashCode | | public int hashCode()(Code) | | Answers 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.
the receiver's hash
See Also: Byte.equals |
| intValue | | public int intValue()(Code) | | Answers the int value which the receiver represents
int the value of the receiver. |
| longValue | | public long longValue()(Code) | | Answers the long value which the receiver represents
long the value of the receiver. |
| parseByte | | public static byte parseByte(String string) throws NumberFormatException(Code) | | Parses the string argument as if it was a byte value and returns the
result. Throws NumberFormatException if the string does not represent a
single byte quantity.
Parameters:
string - a string representation of a single byte quantity. byte the value represented by the argument
throws:
NumberFormatException - if the argument could not be parsed as a byte quantity. |
| parseByte | | public static byte parseByte(String string, int radix) throws NumberFormatException(Code) | | Parses the string argument as if it was a byte value and returns the
result. Throws NumberFormatException if the string does not represent a
single byte quantity. The second argument specifies the radix to use when
parsing the value.
Parameters:
string - a string representation of a single byte quantity.
Parameters:
radix - the radix to use when parsing. byte the value represented by the argument
throws:
NumberFormatException - if the argument could not be parsed as a byte quantity. |
| shortValue | | public short shortValue()(Code) | | Answers the short value which the receiver represents
short the value of the receiver. |
| toString | | public String toString()(Code) | | Answers a string containing a concise, human-readable description of the
receiver.
a printable representation for the receiver. |
| toString | | public static String toString(byte value)(Code) | | Answers a string containing a concise, human-readable description of the
argument.
Parameters:
value - byte the byte to convert. String a printable representation for the byte. |
| valueOf | | public static Byte valueOf(String string) throws NumberFormatException(Code) | | Parses the string argument as if it was a byte value and returns a Byte
representing the result. Throws NumberFormatException if the string
cannot be parsed as a byte quantity.
Parameters:
string - a string representation of a single byte quantity. Byte the value represented by the argument
throws:
NumberFormatException - if the argument could not be parsed as a byte quantity. |
| valueOf | | public static Byte valueOf(String string, int radix) throws NumberFormatException(Code) | | Parses the string argument as if it was a byte value and returns a Byte
representing the result. Throws NumberFormatException if the string
cannot be parsed as a byte quantity. The second argument specifies the
radix to use when parsing the value.
Parameters:
string - a string representation of a single byte quantity.
Parameters:
radix - the radix to use when parsing. Byte the value represented by the argument
throws:
NumberFormatException - if the argument could not be parsed as a byte quantity. |
| valueOf | | public static Byte valueOf(byte b)(Code) | | Returns a Byte instance for the byte value
passed. This method is preferred over the constructor, as this method may
maintain a cache of instances.
Parameters:
b - The byte value. A Byte instance.
