create an ArrayList, with a hashmap in each value

Question

I am looking to create an arraylist, with a hashmap in each value. Not sure how to even start this? Anybody have some old code, or can help out?

In Java

ArrayList<Map<Integer, String>> list = new Arraylist<>();
list.add(new HashMap<Integer, String>());
list.get(0).put(1, "Value");

With generic in Java:

ArrayList<HashMap<Integer,String>> david = new ArrayList<HashMap<Integer,String>>();
david.add(new HashMap<Integer,String>());
