10        sharesTraded = shares;
11    }
12}
13public class Test {

15        var map = new LinkedHashMap<String, Integer>();
16        for (Stock s : stockList) {

18        }
19        for (Map.Entry<String, Integer> e : map.entrySet()) {
20            System.out.println(e.getKey() + " = " + e.getValue());
