 o MAX_VALUE
 public static final byte MAX_VALUE
The maximum value a Byte can have.

 o TYPE
 public static final Class TYPE
The Class object representing the primitive type byte.

Constructors

 o Byte
 public Byte(byte value)
Constructs a Byte object initialized to the specified byte value.

Parameters:
value - the initial value of the Byte
 o Byte
 public Byte(String s) throws NumberFormatException
Constructs a Byte object initialized to the value specified by the String parameter. The radix is assumed to be 10.

Parameters:
s - the String to be converted to a Byte
Throws: NumberFormatException
If the String does not contain a parsable byte.

Methods

 o toString
 public static String toString(byte b)
Returns a new String object representing the specified Byte. The radix is assumed to be 10.

Parameters:
b - the byte to be converted
 o parseByte
 public static byte parseByte(String s) throws NumberFormatException
Assuming the specified String represents a byte, returns that byte's value. Throws an exception if the String cannot be parsed as a byte. The radix is assumed to be 10.

Parameters:
s - the String containing the byte
Throws: NumberFormatException
If the string does not contain a parsable byte.
 o parseByte
 public static byte parseByte(String s,
                              int radix) throws NumberFormatException
Assuming the specified String represents a byte, returns that byte's value. Throws an exception if the String cannot be parsed as a byte.

Parameters:
s - the String containing the byte
radix - the radix to be used
Throws: NumberFormatException
If the String does not contain a parsable byte.
 o valueOf
 public static Byte valueOf(String s,
                            int radix) throws NumberFormatException
Assuming the specified String represents a byte, returns a new Byte object initialized to that value. Throws an exception if the String cannot be parsed as a byte.

Parameters:
s - the String containing the integer
radix - the radix to be used
Throws: NumberFormatException
If the String does not contain a parsable byte.
 o valueOf
 public static Byte valueOf(String s) throws NumberFormatException
Assuming the specified String represents a byte, returns a new Byte object initialized to that value. Throws an exception if the String cannot be parsed as a byte. The radix is assumed to be 10.

Parameters:
s - the String containing the integer
Throws: NumberFormatException
If the String does not contain a parsable byte.
