The Farm

🐖 🦃

Overview

This project represents a simple API for managing barns and their animal inhabitants on a hypothetical farm. There are a number of rules and restrictions about how animals should be organized within the farm's array of colored barns. These specifications are outlined in detail within the comments surrounding AnimalService.

When you're finished you should have an implementation for each of the methods within the AnimalService interface, which is located at com.logicgate.farm.service. The implementing class, AnimalServiceImpl, has already been created next to the interface and lined with TODOs. In addition to adding code to the service class, you may want to add some additional methods to both the FarmRepository and AnimalRepository which can be located at com.logicgate.farm.repository. While the service implementation can be completed successfully without doing so and relying exclusively on the repositories' inherited methods (e.g. findAll(), getOne(), save(), and delete()) your solution may be cleaner and/or more efficient by adding repository methods. Your solution should not need any type of nested iteration.

Rules and Testing

The project has some pre-built tests that can serve to check your work. Feel free to add additional tests if it helps you work through the problem. You're also welcome to modify the existing tests, but you may lose the ability to reliably validate your solution. If you're stuck or confused about any of the requirements it can be helpful to analyze the test as a means to "work backwards" to a solution. To run the tests, simply execute ./gradlew cleanTest test from the project root.

You must:

• use streams

You may:

• add any additional methods or classes to project files
• add external libraries to the project

You may not:

• modify entity classes
• reformat the files

Summary

The primary goal of this exercise is to demonstrate your ability to problem solve and write well-organized code. If you are new to Spring Boot, Gradle or Java you may have to browse documentation for syntax, but the high-level concepts of the exercise are intended to be platform agnostic. If you have a brilliant way to solve the challenge, but can't quite figure out how to fit your solution into the framework please leave behind comments that highlight what you want to do and where you are blocked along the way.
