If it's work work, you *really* should be using generics.
Raw types are still supported in Java, yes -- for compatibility
with existing code from more than thirteen years ago. New code,
even ten-year-old code, should not be using them except in dire
dire dire circumstances. So:
ArrayList list1 = new ArrayList()
should have been something like
List<List<String>> list1 = new ArrayList<>();
or
List<Collection<String>> list1 = new ArrayList<>();
or even
List<Iterable<String>> list1 = new ArrayList<>();
and
ArrayList list2 = new ArrayList()
should have been
List<String> list2 = new ArrayList<>();
or maybe
Collection<String> list2 = new ArrayList<>();
... and, of course, other variations are possible.
