I do nothing more as usual, I only hide the things that are not
important.
It is a bit like generics: first you needed to define the type on both
sides of the statement, now only at one.
With try with resources you never (I think) need a Statement. The
Statement is needed for the ResultSet. So I only want to create the
ResultSet and let it handle the implicit Statement.

If you need 10 ResultSets, you also need 10 Statements. That was the
reason I started with this exercise. And if I need 10 ResultSets, I
just saved typing in the code for getting 10 Statements. I am happy.
:-D
Also: with the not really needed Statements you increase the risk of
bugs.
