MIN_VALUE

public static final byte MIN_VALUE


The minimum value a Byte can have.


MAX_VALUE

public static final byte MAX_VALUE


The maximum value a Byte can have.


TYPE

public static final Class TYPE


The Class object representing the primitive type byte.







Byte

public Byte(byte value)


Constructs a Byte object initialized to the specified byte value.


Parameters:
value - the initial value of the Byte



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.







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



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.



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.



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.



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.
