Byte Class Fields in Java with example

The Byte class wraps a value of primitive type byte in an object.

Following are the fields for 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.

Example

Let us now see an example −

 Live Demo

import java.lang.*; public class Demo {    public static void main(String[] args){       Byte b1, b2;       int i1, i2;       b1 = new Byte("1");       b2 = Byte.MIN_VALUE;       i1 = b1.intValue();       i2 = b2.intValue();       String str1 = "int value of Byte " + b1 + " is " + i1;       String str2 = "int value of Byte " + b2 + " is " + i2;       System.out.println( str1 );       System.out.println( str2 );    } }

Output

This will produce the following output -

int value of Byte 1 is 1 int value of Byte -128 is -128

Example

Let us now see another example −

 Live Demo

import java.lang.*; public class Demo {    public static void main(String[] args){       Byte b1, b2;       String s1, s2;       b1 = new Byte("-10");       b2 = Byte.MIN_VALUE;       System.out.println("Number of bits in b1 = "+b1.SIZE );       System.out.println("Number of bits in b2 = "+b2.SIZE );       s1 = b1.toString();       s2 = b2.toString();       String str1 = "String value of Byte " + b1 + " is " + s1;       String str2 = "String value of Byte " + b2 + " is " + s2;       System.out.println( str1 );       System.out.println( str2 );    } }

Output

This will produce the following output -

Number of bits in b1 = 8 Number of bits in b2 = 8 String value of Byte -10 is -10 String value of Byte -128 is -128
