Wrapper class: Byte class example in java

 The Byte class encapsulates a byte value. It defines the constants MAX_VALUE and MIN_VALUE and provides these constructors:

      Byte(byte b)

      Byte(String str)

Here, b is a byte value and str is the string equivalent of a byte value. 

EX :

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

import java.util.*; public class Byte_Demo {     public static void main(String args[])     {         Byte b1 = new Byte((byte)120);         for(int i = 125; i<=135; i++)         {             Byte b2 = new Byte((byte)i);             System.out.println("b2 = " + b2);         }         System.out.println("b1 Object = " + b1);         System.out.println("Minimum Value of Byte = " + Byte.MIN_VALUE);         System.out.println("Maximum Value of Byte = " + Byte.MAX_VALUE);         System.out.println("b1* 2 = " + b1*2);         System.out.println("b1* 2 = " + b1.byteValue()*2);         Byte b3 = new Byte("120");         System.out.println("b3 Object = " + b3);         System.out.println("(b1==b3)? " + b1.equals(b3));         System.out.println("(b1.compareTo(b3)? " + b1.compareTo(b3));          /*Returns 0 if equal. Returns -1 if b1 is less than b3 and 1 if b1 is         greater than 1*/     } }

Output :

 

b2 = 125

b2 = 126

b2 = 127

b2 = -128

b2 = -127

b2 = -126

b2 = -125

b2 = -124

b2 = -123

b2 = -122

b2 = -121

b1 Object = 120

Minimum Value of Byte = -128

Maximum Value of Byte = 127

b1* 2 = 240

b1* 2 = 240

b3 Object = 120

(b1==b3)? true

(b1.compareTo(b3)? 0
