Byte

BYTES

int BYTES

The number of bytes used to represent a byte value in two's complement binary form.

Constant Value: 1 (0x00000001)

MAX_VALUE

byte MAX_VALUE

A constant holding the maximum value a byte can have, 2⁷-1.

Constant Value: 127 (0x0000007f)

MIN_VALUE

byte MIN_VALUE

A constant holding the minimum value a byte can have, -2⁷.

Constant Value: -128 (0xffffff80)

SIZE

int SIZE

The number of bits used to represent a byte value in two's complement binary form.

Constant Value: 8 (0x00000008)

TYPE

Class<Byte> TYPE

The Class instance representing the primitive type byte.

Byte

Byte (byte value)

Constructs a newly allocated Byte object that represents the specified byte value.

Byte

Byte (String s)

Constructs a newly allocated Byte object that represents the byte value indicated by the String parameter. The string is converted to a byte value in exactly the manner used by the parseByte method for radix 10.

byteValue

byte byteValue ()

Returns the value of this Byte as a byte.

compare

int compare (byte x, 
                byte y)

Compares two byte values numerically. The value returned is identical to what would be returned by:

    Byte.valueOf(x).compareTo(Byte.valueOf(y))
 

compareTo

int compareTo (Byte anotherByte)

Compares two Byte objects numerically.

decode

Byte decode (String nm)

Decodes a String into a Byte. Accepts decimal, hexadecimal, and octal numbers given by the following grammar:

DecodableString:

Sign_opt DecimalNumeral

Sign_opt 0x HexDigits

Sign_opt 0X HexDigits

Sign_opt # HexDigits

Sign_opt 0 OctalDigits

Sign:

-

+

The sequence of characters following an optional sign and/or radix specifier ("0x", "0X", "#", or leading zero) is parsed as by the Byte.parseByte method with the indicated radix (10, 16, or 8). This sequence of characters must represent a positive value or a NumberFormatException will be thrown. The result is negated if first character of the specified String is the minus sign. No whitespace characters are permitted in the String.

doubleValue

double doubleValue ()

Returns the value of this Byte as a double.

equals

boolean equals (Object obj)

Compares this object to the specified object. The result is true if and only if the argument is not null and is a Byte object that contains the same byte value as this object.

floatValue

float floatValue ()

Returns the value of this Byte as a float.

hashCode

int hashCode ()

Returns a hash code for this Byte; equal to the result of invoking intValue().

hashCode

int hashCode (byte value)

Returns a hash code for a byte value; compatible with Byte.hashCode().

intValue

int intValue ()

Returns the value of this Byte as an int.

longValue

long longValue ()

Returns the value of this Byte as a long.

parseByte

byte parseByte (String s)

Parses the string argument as a signed decimal byte. The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value or an ASCII plus sign '+' ('\u002B') to indicate a positive value. The resulting byte value is returned, exactly as if the argument and the radix 10 were given as arguments to the parseByte(java.lang.String, int) method.

parseByte

byte parseByte (String s, 
                int radix)

Parses the string argument as a signed byte in the radix specified by the second argument. The characters in the string must all be digits, of the specified radix (as determined by whether digit(char, int) returns a nonnegative value) except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value or an ASCII plus sign '+' ('\u002B') to indicate a positive value. The resulting byte value is returned.

An exception of type NumberFormatException is thrown if any of the following situations occurs:

• The first argument is null or is a string of length zero.
• The radix is either smaller than MIN_RADIX or larger than MAX_RADIX.
• Any character of the string is not a digit of the specified radix, except that the first character may be a minus sign '-' ('\u002D') or plus sign '+' ('\u002B') provided that the string is longer than length 1.
• The value represented by the string is not a value of type byte.

shortValue

short shortValue ()

Returns the value of this Byte as a short.

toString

String toString ()

Returns a String object representing this Byte's value. The value is converted to signed decimal representation and returned as a string, exactly as if the byte value were given as an argument to the toString(byte) method.

toString

String toString (byte b)

Returns a new String object representing the specified byte. The radix is assumed to be 10.

valueOf

Byte valueOf (String s)

Returns a Byte object holding the value given by the specified String. The argument is interpreted as representing a signed decimal byte, exactly as if the argument were given to the parseByte(java.lang.String) method. The result is a Byte object that represents the byte value specified by the string.

In other words, this method returns a Byte object equal to the value of:

new Byte(Byte.parseByte(s))

valueOf

Byte valueOf (String s, 
                int radix)

Returns a Byte object holding the value extracted from the specified String when parsed with the radix given by the second argument. The first argument is interpreted as representing a signed byte in the radix specified by the second argument, exactly as if the argument were given to the parseByte(java.lang.String, int) method. The result is a Byte object that represents the byte value specified by the string.

In other words, this method returns a Byte object equal to the value of:

new Byte(Byte.parseByte(s, radix))

valueOf

Byte valueOf (byte b)

Returns a Byte instance representing the specified byte value. If a new Byte instance is not required, this method should generally be used in preference to the constructor Byte(byte), as this method is likely to yield significantly better space and time performance since all byte values are cached.
