utilizing JPA Named Queries

When I create an Entity class from a database in NetBeans, it gives me the option to create Named Queries from persistent fields. Accordingly, I see these named queries listed at the top of my Entity class.

What exactly are these queries, and how can I utilize/"call" them?

I'm aware this question is more general than is preferred on SO, so I'm happy to accept a link to a tutorial that answers these questions, but I've been unable to find one myself.

See

If you have:

@NamedQuery(name="Country.findAll", query="SELECT c FROM Country c")
public class Country {
  ...
}

Use with:

TypedQuery<Country> query = em.createNamedQuery("Country.findAll",Country.class);
List<Country> results = query.getResultList();
