Constants

public static final byte MAX_VALUE

Constant for the maximum byte value, 2⁷-1.

Constant Value: 127 (0x0000007f)

public static final byte MIN_VALUE

Constant for the minimum byte value, -2⁷.

Constant Value: -128 (0xffffff80)

public static final int SIZE

Constant for the number of bits to represent a byte in two's compliment form.

Constant Value: 8 (0x00000008)

public static final Class TYPE

The java.lang.Class that represents this class.

Public Constructors

public Byte(byte value)

Constructs a new instance of the receiver which represents the byte valued argument.

Parameters

value	the byte to store in the new instance.

public Byte(String string)

Constructs a new instance of this class given a string.

Parameters

string	a string representation of a single byte quantity.

Throws

NumberFormatException	if the argument could not be parsed as a byte quantity.

Public Methods

public byte byteValue()

Answers the byte value which the receiver represents

Returns

byte the value of the receiver.

public int compareTo(Byte object)

Compares this Byte to the Byte passed. If this instance's value is equal to the value of the instance passed, then 0 is returned. If this instance's value is less than the value of the instance passed, then a negative value is returned. If this instance's value is greater than the value of the instance passed, then a positive value is returned.

Parameters

object	The instance to compare to.

Throws

NullPointerException	if `object` is `null`.

public static Byte decode(String string)

Parses the string argument as if it was a byte value and returns the result. It is an error if the received string does not contain a representation of a single byte quantity. The string may be a hexadecimal ("0x..."), octal ("0..."), or decimal ("...") representation of a byte.

Parameters

string	a string representation of a single byte quantity.

Returns

Byte the value represented by the argument

Throws

NumberFormatException	if the argument could not be parsed as a byte quantity.

public double doubleValue()

Answers the double value which the receiver represents

Returns

double the value of the receiver.

public boolean equals(Object object)

Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.

In this case, the argument must also be a Byte, and the receiver and argument must represent the same byte value.

Parameters

object	the object to compare with this object

Returns

true if the object is the same as this object false if it is different from this object

public float floatValue()

Answers the float value which the receiver represents

Returns

float the value of the receiver.

public int hashCode()

Answers an integer hash code for the receiver. Any two objects which answer true when passed to equals must answer the same value for this method.

Returns

the receiver's hash

public int intValue()

Answers the int value which the receiver represents

Returns

int the value of the receiver.

public long longValue()

Answers the long value which the receiver represents

Returns

long the value of the receiver.

public static byte parseByte(String string, int radix)

Parses the string argument as if it was a byte value and returns the result. Throws NumberFormatException if the string does not represent a single byte quantity. The second argument specifies the radix to use when parsing the value.

Parameters

string	a string representation of a single byte quantity.
radix	the radix to use when parsing.

Returns

byte the value represented by the argument

Throws

NumberFormatException	if the argument could not be parsed as a byte quantity.

public static byte parseByte(String string)

Parses the string argument as if it was a byte value and returns the result. Throws NumberFormatException if the string does not represent a single byte quantity.

Parameters

string	a string representation of a single byte quantity.

Returns

byte the value represented by the argument

Throws

NumberFormatException	if the argument could not be parsed as a byte quantity.

public short shortValue()

Answers the short value which the receiver represents

Returns

short the value of the receiver.

public String toString()

Answers a string containing a concise, human-readable description of the receiver.

Returns

a printable representation for the receiver.

public static String toString(byte value)

Answers a string containing a concise, human-readable description of the argument.

Parameters

value	byte the byte to convert.

Returns

String a printable representation for the byte.

public static Byte valueOf(String string, int radix)

Parses the string argument as if it was a byte value and returns a Byte representing the result. Throws NumberFormatException if the string cannot be parsed as a byte quantity. The second argument specifies the radix to use when parsing the value.

Parameters

string	a string representation of a single byte quantity.
radix	the radix to use when parsing.

Returns

Byte the value represented by the argument

Throws

NumberFormatException	if the argument could not be parsed as a byte quantity.

public static Byte valueOf(String string)

Parses the string argument as if it was a byte value and returns a Byte representing the result. Throws NumberFormatException if the string cannot be parsed as a byte quantity.

Parameters

string	a string representation of a single byte quantity.

Returns

Byte the value represented by the argument

Throws

NumberFormatException	if the argument could not be parsed as a byte quantity.

public static Byte valueOf(byte b)

Returns a Byte instance for the byte value passed. This method is preferred over the constructor, as this method may maintain a cache of instances.

Parameters

b	The byte value.

Returns

A Byte instance.

				int	compareTo(T another)
					Answers an integer indicating the relative positions of the receiver and the argument in the natural order of elements of the receiver's class.


e.g. "intent" or "activity"
