Program:

public class WrapperClassByte {
public static void main(String args[]){

       Byte a=new Byte("4");
       // Byte c=new Byte(4); // no suitable constructor found for Byte(int)
       // Byte d=new Byte('4'); // no suitable constructor found for Byte(char)
       Byte b=2;
       System.out.println(a);
       System.out.println(b);
 }
}

/*
Wrapper class in java provides the mechanism to convert primitive
into object and object into primitive.

Since J2SE 5.0, autoboxing and unboxing feature converts primitive
into object and object into primitive automatically. The automatic
conversion of primitive into object is known as autoboxing
and vice-versa unboxing.
