for (int i=1;i<=10;i++) {
collection.add(i);
        }
System.out.print("Values : ");
//spliterator  split and iterate the split parts in parallel
Spliterator<Integer>str = collection.spliterator();
// if element exists tryAdvance() will perform action
while(str.tryAdvance((n)->System.out.print(n+" ")));

        Information val3 = new Information("17", "Ajeet Kumar Maurya XI", 36);
collection.add(val1);
collection.add(val2);
collection.add(val3);
Spliterator<Information>str = collection.spliterator();
while (str.tryAdvance((n) ->System.out.println(i++ + " ID No = " + n.idNo+ "\n Name = " + n.name + "\n Age = " + n.age+ "\n")))
            ;
    };
}
class Information {
    String idNo, name;
