a). getEntityManager().createQuery(\"select o from User o\");

//Named Query where

Answer 1

Simple Answer: 1) createQuery() - When you want your queries to be executed at runtime.

2) createNamedQuery() - When you want to send common database calls like findBy, findAll,..

3)createNativeQuery() - Used when you want your queries to be database vendor-specific. This brings a challenge of portability.
