Question

Boa noite!

Sou iniciante em Java e aprendendo CRUD em jpa estou com uma dúvida se alguém me ajudar ficaria muito agradecido!

não consigo remover do banco de dados segue o código;

Método remover:

@Override
    public void remover(Cargo cargo) {
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("ProjetoPrimeiroBimestreEmpresaPU");
        EntityManager entityManager = emf.createEntityManager();
        cargo = entityManager.find(Cargo.class, 1L);
        entityManager.getTransaction().begin();
        entityManager.remove(cargo);
        entityManager.getTransaction().commit();
        entityManager.close();
    }

Executável:

public class Principal {
    public static void main(String[] args) {

        Cargo c = new Cargo();
        c.setCodigo(34);
        new CargoDao().remover(c);

       }

}
