Question about modification

#1

Hi, I'm student in Web Apps Developing, I'm trying to use your fucking shit program and I am very close to jump from the window of my school.

What's the problem here?

Thank u Sir.

System.out.println("Entidad a modificar: vehículos || coche || persona || trabajador");
            String entidad = menu.nextLine();
            String vehículos = "vehículos";
            String coche= "coche";
            String persona = "persona";
            String trabajador = "trabajador";
            
            String Id = "Id";
            String matrícula = "matrícula";
            String fechaMatriculación = "fechaMatriculación";
            
            if (entidad == vehículos) {
                System.out.println("Campo a modificar:");
                
            } 
            String campo = menu.next();
                if (campo.equals(Id)) {
                    menu.next();
                    System.out.println("Nuevo valor:");
                    int valor = menu.nextInt();
                    em.getTransaction().begin();
                    Query consulta = em.createQuery("UPDATE vehículos"  + "SET " + campo + "=" + valor + "WHERE id = null");
                    int numeroObjetosModificados = consulta.executeUpdate();
                    em.getTransaction().commit();
                } else {
                    System.out.println("Campo a modificar:");
                    String campo1 = menu.next();
                    if (campo1.equals(matrícula)) {
                        System.out.println("Nuevo valor:");
                        String valor = menu.next();
                        em.getTransaction().begin();
                        Query consulta = em.createQuery("UPDATE " + entidad + "SET " + campo1 + "=" + valor + "WHERE id = 1");
                        int numeroObjetosModificados = consulta.executeUpdate();
                        em.getTransaction().commit();
                    } else {
                        System.out.println("Nuevo valor:");
                        String valor = menu.nextLine();
                        em.getTransaction().begin();
                        Query consulta = em.createQuery("UPDATE "  + "SET fechaMatriculación"  + "=" + valor + "WHERE id = 1");
                        int numeroObjetosModificados = consulta.executeUpdate();
                        em.getTransaction().commit();
                    }
                }

If you really want help you must first improve you communication skills:

  1. Throwing a program that doesn't work with the general question "What's the problem here?", without even explaining what you are trying to do, what is not working, are you getting an error message, exception, etc. is not the right way.
  2. In addition, consider using a more polite language.
