Byte class Methods in Java

java.lang.Byte

The Byte class wraps a value of primitive type byte in an object. An object of type Byte contains a single field whose type is a byte. In addition, this class provides several methods for converting a byte to a String and a String to a byte, as well as other constants and methods useful when dealing with a byte.

Some methods of Byte class

Byte.BYTES: The number of bytes used to represent a byte value in twos-complement binary form.

Byte.compare(): It compares two-byte values numerically.

Byte.compareUnsigned():  It compares two-byte values numerically treating the values as unsigned.

Byte.decode():  It decodes a String into a Byte. Accepts decimal, hexadecimal, and octal number.

Byte.hashCode(): It returns a hash code for a byte value.

Byte.MAX_VALUE: A constant holding the maximum value a byte can have, 2^7-1 (127).

Byte.MIN_VALUE: A constant holding the minimum value a byte can have, -2^7 or (-128).

Byte.parseByte(): It 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 '-' ('\u005Cu002D') to indicate a negative value or an ASCII plus sign '+'('\u005Cu002B') to indicate a positive value.

Byte.parseByte(String s, int radix): It parses the string argument as a signed byte in the radix specified by the second argument.

Byte.SIZE: The number of bits used to represent a byte value in twos-complement binary form.

Byte.toString(): It returns a new String object representing the specified byte. The radix is assumed to be 10.

Byte.toUnsignedInt(): It converts the argument to an int by an unsigned conversion. In an unsigned conversion to an int, the high-order 24 bits of the int are zero and the low-order 8 bits are equal to the bits of the byte argument.

Byte.toUnsignedLong(): It converts the argument to a long by an unsigned conversion. In an unsigned conversion to a long, the high-order 56 bits of the long are zero and the low-order 8 bits are equal to the bits of the byte argument.

Byte.valueOf(byte b): It returns a Byte instance representing the specified byte value.

Byte.valueOf(String s, int radix): It 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.

Byte.valueOf(String s): It returns a Byte object holding the value given by the specified String.
