Byte

public Byte(byte value)

Constructs a Byte object initialized to the specified byte value. value - the initial value of the Byte

Method Detail

byteValue

public byte byteValue()

Returns the value of this Byte as a byte.

Overrides:

byteValue in class Number

equals

public boolean equals(Object obj)

Compares this object to the specified object.

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns a hashcode for this Byte.

Overrides:

hashCode in class Object

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.

Throws:

NumberFormatException

                      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.

Throws:

NumberFormatException

toString

public String toString()

Returns a String object representing this Byte's value.

Overrides:

toString in class Object

valueOf

public static Byte valueOf(byte i)

Returns the object instance of i

Parameters:

i - the primitive

Returns:

object instance

intValue

Specified by:

longValue in class Number

floatValue

public float floatValue()

Specified by:

floatValue in class Number

doubleValue

public double doubleValue()

Specified by:

doubleValue in class Number

compare

public int compare(byte b1,
                   byte b2)

compareTo

public int compareTo(Byte b)

Description copied from interface: Comparable

Compares this object to the specified object to determine their relative order.

Specified by:

compareTo in interface Comparable<Byte>

Parameters:

b - the object to compare to this instance.

Returns:

a negative integer if this instance is less than another; a positive integer if this instance is greater than another; 0 if this instance has the same order as another.
