Try this out :

List<HashMap<String, Object>> list = new ArrayList<HashMap<String, Object>>();

    for (Map element : list) {
        Set<Map.Entry<String, Object>> entrySet = element.entrySet();
        for (Map.Entry<String, Object> mapEntry : entrySet) {
            System.out.println("Key is : " + mapEntry.getKey());
            System.out.println("Value is : " + mapEntry.getValue());
        }
    }
