[AB3: Removing Fields]: Additional Resources and Further Reading Section

[NeoHW]

Current

Given that this resource is shorter and also mostly done as a read-through, it might be helpful to have additional resources.

Problem

Once beginners complete the tutorial, they might be interested in learning more about refactoring techniques, IntelliJ IDEA, or other related topics to improve their skills. With additional suggested resources for further reading, we can provide them with a launchpad for them to further explore on their own.

Proposed

Include a section on additional resources and further reading. Provide links to official IntelliJ IDEA documentation on refactoring tools, articles on refactoring best practices, and tutorials on advanced refactoring techniques.
