Experienced Java developers look to improve their Java skills from time to time; after all, this is a dynamic career path, and you need to keep learning to learn about new and upcoming Java features. Java is the most widely used programming language, so it’s best to spend some time improving your Java skills.
Believe it or not, new Java books are an excellent resource for learning Java because they are written by experts in the field who are highly trusted in the field. Java books are also more detailed and provide more in-depth knowledge than free and online materials.
1.Java concurrency practices
By Brian Goetz with Tim Peierls, Joshua Bloch, Joseph Bowbeer, David Holmes and Doug Lea
It is one of the best Java books to delve into Java concurrency and multithreading. Now some doubt its relevance, but the book was always ahead of its time. When it was first released in 2006, Java developers were still unsure about the new concurrency changes made in Java 1.5
It is still considered one of the most recommended books for Java beginners or mid-level developers who want to master the concept of concurrency. The best part of the book is that it introduces the clear concepts and basics of concurrent programming, such as visibility, sorting, thread safety, immutability, parallelism, and so on.
The only problem with Java concurrency in practice is that some parts of the Java book seem challenging and difficult to understand at first glance. However, the subjects themselves are quite complex. However, if your goal is to learn concurrency and multithreading in Java, it’s one of the best Java books out there, and you’ll realize later that it’s worth solving all the difficult tasks and exercises that come up in this book.
2.Java Performance Companion
By Charlie Hunt and Monica Beckwith
Every Java developer learns how to write code first, then good code, and finally efficient code.
This makes Java books like Java Performance Companion a gold mine for advanced Java developers who are at a stage where they now need to develop a program that can also execute efficiently. Java Performance Companion provides a complete set of garbage collection, JVMS, and other important Java Performance tools. It also covers the details of the G1 garbage collector very extensively.
3. Test-driven: TDD for Java developers and acceptance TDD
The author – Lasse Koskela
Testing is another vast area for Java developers. Test Drive is one of the best Java books to learn how to develop unique automated test programs. This should be a must-read for any Java developer who prioritizes code quality and wants to excel at writing unit, integration, and automated tests.
Unlike many other Java books, Test-Driven:TDD and Acceptance TDD for Java Developers provides various practical examples of test-driven Java code. In addition, the book covers acceptance of test-driven development, the Fit framework, and testing of Java EE components such as servlets, JSPS, and Spring controllers.
4.Java Performance: The Definitive guide
By Scott Ochs
If you want to learn about garbage collection, the JVM, and other performance tuning aspects of the Java programming language, Java performance is another of the best books on Java. It covers all three Java topics in a very simple and effective way. It is a great guide to understanding the various ways to maximize Java threading and synchronization performance features, improve the performance of Java-driven database applications, and how to solve performance problems in Java EE and Java SE apis.
5. Effective Java
By Joshua Bloch
Effective Java is one of the most distinctive Java books. It is a must-have book for any Java programmer, experienced or beginner, who needs a perspective shift on programming and has problems understanding problems. This is the kind of Java book that will correct your thinking about handling and solving Java problems.
Unlike any other Java book, it is an important resource for a wealth of practical guides, including specific and step-by-step instructions for solving some of the most common problems. It has the power to enable developers to start solving problems in different but effective ways.
