Java.lang.Byte Class

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 −

pubpc 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

Sr.No.	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.

Sr.No.

Constructor & Description

Byte(byte value)

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

Byte(String s)

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

Class methods

Sr.No.	Method & Description
1	byte byteValue() This method returns the value of this Byte as a byte.
2	int compareTo(Byte anotherByte) This method compares two Byte objects numerically.
3	static Byte decode(String nm) This method decodes a String into a Byte.
4	double doubleValue() This method returns the value of this Byte as a double.
5	boolean equals(Object obj) This method compares this object to the specified object.
6	float floatValue() This method returns the value of this Byte as a float.
7	int hashCode() This method returns a hash code for this Byte.
8	int intValue() This method returns the value of this Byte as an int.
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	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	This method returns a Byte object holding the value extracted from the specified String when parsed with the radix given by the second argument.
