Java.lang.Byte Class

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:

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
1Byte(byte value)

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

2Byte(String s)

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

Class methods

S.N.Method & Description
1byte byteValue()

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

2int compareTo(Byte anotherByte)

This method compares two Byte objects numerically.

3static Byte decode(String nm)

This method decodes a String into a Byte.

4double doubleValue()

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

5boolean equals(Object obj)

This method compares this object to the specified object.

6float floatValue()

7int hashCode()

This method returns a hash code for this Byte.

8int intValue()

This method returns the value of this Byte as an int.

9long longValue()

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

10static byte parseByte(String s)

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

11static byte parseByte(String s, int radix)

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

12short shortValue()

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

13String toString()

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

14static String toString(byte b)

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

15static Byte valueOf(byte b)

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

16static Byte valueOf(String s)

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

17static 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.
