Introduction

The java.lang.Byte class wraps a value of primitive type byte in an object. An object of type Byte contains a single field whose type is byte.

Class declaration

Following is the declaration for java.lang.Byte class:

public final class Byte
   extends Number
      implements Comparable<Byte>

Field

Following are the fields for java.lang.Byte class:

  • static byte MAX_VALUE -- This is constant holding the maximum value a byte can have, 27-1.

  • static byte MIN_VALUE -- This is constant holding the minimum value a byte can have, -27.

  • static int SIZE -- This is the number of bits used to represent a byte value in two's complement binary form.

  • static Class<Byte> TYPE -- This is the Class instance representing the primitive type byte.

Class constructors

S.N. Constructor & Description
1

Byte(byte value)

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

2

Byte(String s)

This constructs a newly allocated Byte object that represents the byte value indicated by the String parameter.

9

long longValue()

This method returns the value of this Byte as a long.

10

static byte parseByte(String s)

This method parses the string argument as a signed decimal byte.

11

static byte parseByte(String s, int radix)

This method parses the string argument as a signed byte in the radix specified by the second argument.

12

short shortValue()

This method returns the value of this Byte as a short.

13

String toString()

This method returns a String object representing this Byte's value.

14

static String toString(byte b)

This method returns a new String object representing the specified byte.

15

static Byte valueOf(byte b)

This method returns a Byte instance representing the specified byte value.

16

static Byte valueOf(String s)

This method returns a Byte object holding the value given by the specified String.

17

static Byte valueOf(String s, int radix)

This method returns a Byte object holding the value extracted from the specified String when parsed with the radix given by the second argument.
