{
public static void main(String args[])
{
Integer a=new Integer(12);
System.out.println(a);

int a1=10;
a=a1;//Auto boxing
System.out.println(a);

Boolean b1=new Boolean(true);
boolean b2=false;
b2=b1;//Unboxing
System.out.println(b1);

}
}


exapmle2:-

class Demo2
{
public static void main(String args[])
{
Boolean b=new Boolean("java");
if(b)//unboxing
{
System.out.println("s");
}
if(b=true)//Autoboxing
{
System.out.println("A");
