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
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.
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()
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.
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.
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.
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.
