class Main {
  public static void main(String[] args) {
    // create primitive types
    int a = 5;
    double b = 5.65;

    //converts into wrapper objects
    Integer aObj = Integer.valueOf(a);
    Double bObj = Double.valueOf(b);

    if(aObj instanceof Integer) {
      System.out.println("An object of Integer is created.");
    }

    if(bObj instanceof Double) {
      System.out.println("An object of Double is created.");
    }
