   * {@code Optional} class. However, this common usage:
   *
   * {@snippet :
   * for (Foo foo : possibleFoo.asSet()) {
   *   doSomethingWith(foo);
   * }
   * }
   *
   * ... can be replaced with:
   *
   * {@snippet :
   * possibleFoo.ifPresent(foo -> doSomethingWith(foo));
   * }
   *
   * <p><b>Java 9 users:</b> some use cases can be written with calls to {@code optional.stream()}.

Тоді, у випадку URL:

```
http://localhost:8000/items/?q=foo&q=bar
```

ви отримаєте кілька значень `q` query параметрів (`foo` і `bar`) у вигляді Python `list` у вашій функції операції шляху, у параметрі функції `q`.

Отже, відповідь на цей URL буде:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

```
http://localhost:8000/items/?q=foo&q=bar
```

würden Sie die mehreren `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-`list` in Ihrer *Pfadoperation-Funktion* im *Funktionsparameter* `q` erhalten.

So wäre die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> zu dieser URL:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

Então, com uma URL como:

```
http://localhost:8000/items/?q=foo&q=bar
```

você receberia os múltiplos valores dos parâmetros de consulta `q` (`foo` e `bar`) em uma `list` Python dentro da sua função de operação de rota, no parâmetro da função `q`.

Assim, a resposta para essa URL seria:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```
