Moderne Versionen von Python unterstützen **„asynchronen Code“** unter Verwendung sogenannter **„Coroutinen“** mithilfe der Syntax **`async`** und **`await`**.

Nehmen wir obigen Satz in den folgenden Abschnitten Schritt für Schritt unter die Lupe:

* **Asynchroner Code**
* **`async` und `await`**
* **Coroutinen**

## Asynchroner Code

 * override {@code offer} as well.

 * <p><b>{@code default} method warning:</b> This class does <i>not</i> forward calls to {@code
 * default} methods. Instead, it inherits their default implementations. When those implementations
 * invoke methods, they invoke methods on the {@code ForwardingDeque}.

The return type of `HttpUrl.queryParameterValues()` is `List<String?>`. Lists that may contain null
are uncommon and Kotlin callers may have incorrectly assigned the result to `List<String>`.


Code Cleanup
------------

IntelliJ and Android Studio offer a **Code Cleanup** feature that will automatically update
deprecated APIs with their replacements. Access this feature from the _Search Anywhere_ dialog
(double-press shift) or under the _Analyze_ menu.

## 数値の検証: 浮動小数点、 大なり小なり

数値のバリデーションは`float`の値に対しても有効です。

ここで重要になってくるのは<abbr title="より大きい"><code>gt</code></abbr>だけでなく<abbr title="以下"><code>ge</code></abbr>も宣言できることです。これと同様に、例えば、値が`1`より小さくても`0`より大きくなければならないことを要求することができます。

したがって、`0.5`は有効な値ですが、`0.0`や`0`はそうではありません。

これは<abbr title="未満"><code>lt</code></abbr>も同じです。
