The Byte class is the standard wrapper for byte values.
Number, Serialized Form| Field Summary | |
static byte |
MAX_VALUE
The maximum value a Byte can have. |
static byte |
MIN_VALUE
The minimum value a Byte can have. |
static Class |
TYPE

| Constructor Summary | |
Byte(byte value)
Constructs a Byte object initialized to the specified byte value. |
|
Byte(String s)

public static Byte decode(String nm)
throws NumberFormatException
String into a Byte. Accepts
decimal, hexadecimal, and octal numbers, in the following formats:
[-] decimal constant
[-] 0x hex constant
[-] # hex constant
[-] 0 octal constant
The constant following an (optional) negative sign and/or "radix
specifier" is parsed as by the Byte.parseByte method
with the specified radix (10, 8 or 16). This constant must be positive
or a NumberFormatException will result. The result is made negative if
first character of the specified String is the negative
sign. No whitespace characters are permitted in the
String.nm - the String to decode.Byte represented by the specified string.NumberFormatException - if the String does not
contain a parsable byte.parseByte(String, int)public byte byteValue()
