I am beginning to understand ENUMs but I don’t know if what I want to try to do is not possible, I need to create an object that has an enum, that object is then added to an array, but I am also occupying binary files, so when saving the enum with an .ordinal if I can, but when I read it and want to convert it to the enum type I can no longer and the object or the array is not created

    public void leer() throws FileNotFoundException, IOException {
        FileInputStream listaCliente = new FileInputStream("ListaClientes.prod");
        FileInputStream listaAuto = new FileInputStream("ListaAutos.prod");
        DataInputStream buffer = new DataInputStream(listaCliente);
        DataInputStream buffer2 = new DataInputStream(listaAuto);
        while (buffer.available() > 0) {
            String nombre = buffer.readUTF();
            int licencia = buffer.readInt();

            Cliente cliente = new Cliente(nombre, licencia);
            Renta.listaClientes.add(cliente);
        }
        while (buffer2.available() > 0) {
            String marca = buffer2.readUTF();
            String placa = buffer2.readUTF();
            int modelo = buffer2.readInt();
            double capacidad = buffer2.readDouble();
            double kilometraje = buffer2.readDouble();
            int tipo2 = buffer2.readInt();
            TipoAuto tipo = TipoAuto.values()[tipo2];
            Autos auto = new Autos(marca, modelo, placa, capacidad, kilometraje, tipo);
            System.out.println("el arreglo" + marca +" ," +modelo+" , "+placa+","+capacidad+","+kilometraje+","+tipo);
            Renta.listaAutos.add(auto);

        }
        
    }
