Hashmap inside a Arraylist

hI,

I have a hashmap which has username and password information.
Map mapDetail = new HashMap();
mapDetail.put("username",username);
mapDetail.put("password",password);
HashMap is embedded in a arraylist like below
List missingList = new ArrayList();
missingList.add(mapDetail);

I need to read the username and password information to send it to one other java program. How can I achieve it.Any ideas, suggestions, sample code, links, source code highly appreciated. Thanks in advance

where can I find more of these kind of examples. I need to become more knowledgeable in this area of collection where passing 2D collection object into 1D collection object and reading back again. please advise

My example should be more generic really:

      for (Map<String, String> m : maps) {
            for (Map.Entry<String, String> e : m.entrySet()) {
                String key = e.getKey();
                String val = e.getValue();
                System.out.printf("key=%s,value=%s\n", key, val);
            }
        }
