Constructor Detail

Byte

public Byte(byte value)

Constructs a Byte object initialized to the specified byte value.

Parameters:

value - the initial value of the Byte

Method Detail

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

Returns:

the parsed value of 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

Returns:

the parsed value of the byte

Throws:

NumberFormatException - If the String does not contain a parsable byte.

byteValue

public byte byteValue()

Returns the value of this Byte as a byte.

Returns:

the value of this Byte as a byte.

toString

public String toString()

Returns a String object representing this Byte's value.

Overrides:

toString in class Object

Returns:

a string representation of the object.

hashCode

public int hashCode()

Returns a hashcode for this Byte.

Overrides:

hashCode in class Object
