Entity result = (Entity) query.uniqueResult();

Query query = entityManager.createQuery("SELECT e FROM Entity e WHERE e.id = :id");
query.setParameter("id", entityId);
query.setMaxResults(1);
List<Entity> results = query.getResultList();
Entity result = results.isEmpty() ? null : results.get(0);

TypedQuery<Entity> query = entityManager.createQuery("SELECT e FROM Entity e WHERE e.id = :id", Entity.class);
query.setParameter("id", entityId);
Entity result = query.getSingleResult();
