def say_hi(name: Optional[str]):
    print(f"Hey {name}!")
```

The parameter `name` is defined as `Optional[str]`, but it is **not optional**, you cannot call the function without the parameter:

```Python
say_hi()  # Oh, no, this throws an error! 😱
```

The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:

```Python

    assertEquals(6, (int) future.get());
  }

  public void testSameThreadScheduledExecutorWithException() throws InterruptedException {
    Runnable runnable =
        () -> {
          throw new RuntimeException("Oh no!");
        };

    Future<?> future = TestingExecutors.sameThreadScheduledExecutor().submit(runnable);
    assertThrows(ExecutionException.class, future::get);
  }

    assertEquals(6, (int) future.get());
  }

    Runnable runnable =
        () -> {

        };

    Future<?> future = TestingExecutors.sameThreadScheduledExecutor().submit(runnable);
    assertThrows(ExecutionException.class, future::get);

El parámetro `name` está definido como `Optional[str]`, pero **no es opcional**, no puedes llamar a la función sin el parámetro:

```Python
say_hi()  # ¡Oh, no, esto lanza un error! 😱
```

El parámetro `name` **sigue siendo requerido** (no es *opcional*) porque no tiene un valor por defecto. Aun así, `name` acepta `None` como valor:
