As a developer, it’s of the highest importance to expand, improve and refine your skills. After all, a software developer should always strive for true craftsmanship. One way of doing that? Read books! This article is an updated version of our “Interesting books for junior java developers” article.

There’s an abundance of great – and less great – online resources which can be used to facilitate this process. However, with these type of resources, you often jump from one tutorial to the other.  Each time you have to deal with a different author whose opinionated view and approach can differ from the previous author’s. This might leave you unnecessarily confused and it might prove more difficult this way to get a good overview of the subject you’re studying. This is why books still are very relevant and useful when learning new subjects related to software development. Books offer authors with – almost always – a proven track-record, a consistent view, a consistent approach and a full and in-depth coverage of the subject.

Below, you’ll find a list of both recent (and also some older) books that are very relevant to junior (java) software developers at the start of their professional career, willing to hone their skills. Happy reading!

Soft Skills: The software developer’s life manual

Although the author can have a very lone-wolf / survival-of-the-fittest view on certain subjects – which I don’t share – this book was at the very least an interesting read.

Soft Skills: The software developer’s life manual is a unique guide, offering techniques and practices for a more satisfying life as a professional software developer.
