In the example above, the `sendPhoto` method uses the `photo` parameter using three different supported types.
103115

104-
* `File` will use the File's extension to detect the `Content-Type`.
105-
* `byte[]` will use `application/octet-stream` as `Content-Type`.
106-
* `FormData` will use the `FormData`'s `Content-Type` and `fileName`.
116+
* `File` will use the File's extension to detect the `Content-Type`;
117+
* `byte[]` will use `application/octet-stream` as `Content-Type`;
118+
* `FormData` will use the `FormData`'s `Content-Type` and `fileName`;
119+
* Client's custom POJO for grouping parameters (including types above).
107120

108121
`FormData` is custom object that wraps a `byte[]` and defines a `Content-Type` and `fileName` like this:
109122

110123
```java
111-
FormData formData = new FormData("image/png", "filename.png", myDataAsByteArray);
112-
someApi.sendPhoto(true, formData);
124+
FormData formData = new FormData("image/png", "filename.png", myDataAsByteArray);
125+
someApi.sendPhoto(true, formData);
