#### 기본값과 동일한 값을 갖는 데이터

If the data has the same values as the default ones, like the item with ID `baz`:
ID가 `baz`인 항목(items)처럼 기본값과 동일한 값을 갖는다면:

```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

        final ClassLoader cl2 = new URLClassLoader(new URL[] { new URL("file:/bar") }, cl1);
        final ClassLoader cl3 = new URLClassLoader(new URL[] { new URL("file:/baz") }, cl2);

        final ClassLoaderIterator it = new ClassLoaderIterator(cl3);
        assertThat(it.hasNext(), is(true));
        assertThat(it.next(), is(sameInstance(cl3)));

        assertThat(it.hasNext(), is(true));

        "rock",
        "metal",
        "bar"

    "images": [
        {
            "url": "http://example.com/baz.jpg",
            "name": "The Foo live"
        },
        {
            "url": "http://example.com/dave.jpg",
            "name": "The Baz"
        }
    ]
}
```

!!! info
    Notice how the `images` key now has a list of image objects.
