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.
