There are many causes for an NPE (NullPointerException) but all come from a dereference (using the dot operator) on a reference that is null. An NPE is easy to catch; there is an entire article devoted to it in our 'Insights' section.

Read the API documentation for the Collection interface and the List interface; all you do is add(...) them to your List.
