JAVA wrapper classes and automatically unpack instance code

public class Wrapper {
     public static void main(String[] args) {
         int i = 500;
         Integer t = new Integer(i);
         int j = t.intValue();
         String s = t.toString();
         System.out.println(t);
         Integer t1 = new Integer(500);
         System.out.println(t.equals(t1));
         Integer a1 = 5;
         int a2 = new Integer(5);
         System.out.println("a1 = " + a1 + ",a2 = " + a2);
     }
 }
