List vs List
...
The difference is that, for example, a
List<HashMap<String,String>>
is a
List<? extends Map<String,String>>

Why are private fields private to the type, not the instance?
...ith code in which you have two objects of the same class, then there is no extra dependency. A class always depends on itself.
