If you want to grab a book for web development in Java, then Microservices with Spring Boot is a great option.
Let us get to the details.
Best Books for Learning Java: Beginners Friendly
This is the first section and focuses more on java books for beginners. Most of the books included in this section cover the latest java specifications including Java 9, 10, and Java SE 11.
You will find only a couple of books like Head First Java that still teach java programming using older Java releases and is pending an upgrade.
The simple reason to keep these oldish books is that authors have covered Java fundamentals in a very beginner friendly way with a key motive to teach programming and computer science in general. Also, some of these books continue to be recommended by university professors and are still part of the curriculum.
I would emphasize that selecting the right resource for learning is key to save time and understand the depths of any programming language.

The second half of the book covers topics such as polymorphism, constructors, wrapper classes, exception handling. Having read the initial few chapters, you can get a good understanding of Core Java basics.
The last few chapters cover GUI, Swing, serialization, IO operations, multithreading, basics of socket programming, collections, generics. There are sections dedicated to teaching more about code deployment, distributed computing, basics about servlets, and EJB.
For Java professionals looking to refresh their basics, this is a good book, though it does not cover much about advanced Java topics or real-world scenarios.
Best Java Books for Intermediate and Advanced Level
Here on we will cover books that are helpful to understand intermediate to advanced level Java concepts.
It is also important to understand that not all developers require to get into advanced level concepts. These are typically required if you want to take programming as a profession or working on a project that requires knowledge of advanced programming techniques.
Raoul-Gabriel Urma, Mario Fusco, Alan Mycroft (Manning Publications, November 2018)
The key focus of this book is on the most recent java features including lambda functions, streams, functional programming paradigm, reactive programming techniques, and much more. Authors provide ample examples of how to uses these features to build modern applications.
Reading this book, you will also understand that java is evolving at a fast pace where more features are added with every new version and that some of the old features get deprecated.
Organization of Chapters
Chapter one starts with the fundamentals of Java SE and also includes Java SE version 11. Subsequent chapters cover the most advanced and recently included features of Java. Apart from the latest features of Java, this book also covers other intermediate to advance level topics like collections, refactoring, debugging, date API, etc. and more.
While you would find dedicated chapters on lambda expressions usage, writing multithreaded programs that run on multi-core processors, streams, and asynchronous programming.
Authors have also dedicated a few chapters to the functional programming paradigm and teach how you can use both functional as well as oops paradigms in java applications.
And in the end, you get a good comparison between Java and Scala. Scala is fast becoming the language of choice for functional programming and runs on JVM, so it is worth keeping an eye on that.
Professionals working actively on the latest versions of Java can make the most out of this book. I would easily classify this one as a good book to read in case you are planning to prepare for a Java certification.
It is worth noting that, authors do not go too much into the basics and may not be suited well suited for absolute beginners.

The final chapters cover the ATM case study, Java platform module system, and a dry run on Java 9 basics with more details.
Manning Publications (Lasse Koskela, October 2007)
A lot of Java books have a basic mention of test-driven development with java, but you would not find any book covering TDD in as much detail as this book.
This book is slightly dated now but covers the fundamentals very well and is still relevant to learn TDD in Java.
The book introduces you to concepts such as user acceptance test-driven development, Junit testing, iterative development, the focus is on creating a test environment to improve application design.
This book starts by giving you a big picture of what is TDD and details within it. Next, it provides details on how you can apply TDD to swing and web application development.
Finally, the book covers a lot more about how one can build enterprise-class products with acceptance TDD. More about adopting TDD methodologies.
All said, do not expect the book to cover too much about Java basics, it requires students to be familiar with java programming. Overall a good book to read if you know Java and are looking forward to work on enterprise-level applications.
Java is a high-level programming language and is not that difficult to learn, and for that reason, many students and beginners can self-learn java from a good book.
Also, though there are many online courses and tutorials, books are generally handy, so having a book even if you have subscribed for a training course always helps.
This brings us to the end of our review of the best java books, each book is different and teaches in a different style.
Our recommendation is that you should spend some time to shortlist a couple of books from this article, go to amazon or the publisher’s website, and check out free chapters to see if books fit your style.
