| In |
| [*Detecting Argument Selection Defects*](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/46317.pdf) |
| by Rice et. al., the authors argue that methods should have 5 of fewer |
| parameters (see section 7.1). APIs with larger than this number often lead to |
| parameter mismatch bugs (e.g, calling `create(firstName, lastName)` instead of |
| `create(lastName, firstName)`). |
| |
| In *Effective Java* (Item 2), Bloch recommends "consider[ing] a builder |
| [pattern] when faced with many [constructor] parameters". You may consider |
| encapsulating your parameters into a single |
| [`@AutoValue`](https://github.com/google/auto/tree/master/value) object, which |
| is created using an |
| [AutoValue Builder](https://github.com/google/auto/blob/master/value/userguide/builders.md). |
