### Das Problem reproduzieren

In den meisten Fällen und bei den meisten Fragen ist etwas mit dem von der Person erstellten **eigenen Quellcode** los.

In vielen Fällen wird nur ein Fragment des Codes gepostet, aber das reicht nicht aus, um **das Problem zu reproduzieren**.

////

### Classes as types { #classes-as-types }

You can also declare a class as the type of a variable.

Let's say you have a class `Person`, with a name:

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}

Then you can declare a variable to be of type `Person`:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}

And then, again, you get all the editor support:

        this.registrationId = generateRegistrationId();
        this.shareName = shareName;
        this.serverAddress = serverAddress;
        this.serviceType = serviceType;
        this.version = WitnessVersion.VERSION_2; // Use latest by default
        this.registrationTime = System.currentTimeMillis();
        this.sequenceNumber = new AtomicLong(0);
        this.state = WitnessRegistrationState.REGISTERING;

Le serveur va dans la cuisine 👨‍🍳.

Vous attendez devant le comptoir afin que personne ne prenne vos burgers 🍔 avant vous, vu qu'il n'y a pas de numéro de commande.

* If you can't understand the question, ask for more **details**.

### Reproduce the problem { #reproduce-the-problem }

For most of the cases and most of the questions there's something related to the person's **original code**.

In many cases they will only copy a fragment of the code, but that's not enough to **reproduce the problem**.

            WitnessRegisterMessage message = new WitnessRegisterMessage();
            // Convert int version to WitnessVersion enum
            WitnessVersion witnessVersion = (request.getVersion() >= 0x00020000) ? WitnessVersion.VERSION_2 : WitnessVersion.VERSION_1;
            message.setVersion(witnessVersion);
            message.setNetName(serverAddress.getHostName());
            message.setShareName(request.getShareName());
