            String name = (String) e.nextElement();
            String value = props.getProperty(name);
            if (value == null) {
                value = callback.apply(name);

            } else {

例として次の関数を見てみましょう:

```python
from typing import Optional


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

パラメータ `name` は `Optional[str]` と定義されていますが、任意ではありません。このパラメータなしで関数を呼び出すことはできません:

```Python
say_hi()  # あっ、これはエラーになります！😱
```

`name` パラメータにはデフォルト値がないため、依然として必須（任意ではない）です。ただし、`name` は値として `None` を受け付けます:

```Python
say_hi(name=None)  # これは動作します。None は有効です 🎉
```

    //
    // ----------------------------------------------------------------------

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }
