The best Java books for advanced developers and experts (2023) part 1

Nowadays, when information technology is advancing rapidly, education and learning new things is an essential part of success for all those who work in the field of software development. The IT industry is changing so rapidly that technologies and practices that were relevant a few years ago may be obsolete today. In addition, new technologies, frameworks and tools are constantly emerging that can fundamentally affect the way developers work.

Those who have achieved a certain level of knowledge and experience in Java development may feel comfortable believing that their current knowledge and experience is sufficient to remain relevant in the job market and slip into a comfort zone. However, the IT world is highly competitive, and less experienced developers who are willing to continually educate themselves can quickly acquire new skills and knowledge that would allow them to compete with java developer expert.

While experts may have an advantage in the depth of their knowledge, less experienced developers (e.g., medior java developer) may excel in the speed of adapting and implementing new technologies. Ultimately, the ability to adapt and grow with technological change is what distinguishes true experts from those who stay in their comfort zone and risk making their knowledge obsolete.

The world of Java development is no exception. Every year not only new improvements to the Java language come along, but with them come new books that bring these innovations closer to us in an easy-to-read form. But in today’s dynamic times, when free time is getting scarcer, there are so many books that the problem arises, which books are worth investing not only money, but also precious time.

That’s why we’ve prepared this article, which is aimed at more experienced senior Java developers and all those who would like to learn something new by studying the best books ever written for the advanced Java community.

For a list of books for beginner Java developers, see our previous article Java books for beginners.

Thinking in Java 4th Edition

The book Thinking in Java, written by Bruce Eckel, has generated enthusiasm from developers around the world for its clear explanation of the language’s principles, thoughtfully structured chapters, and many direct programming examples. From the basics of Java syntax to its most advanced features, Thinking in Java is designed to teach you, one simple step at a time.

Fourth edition Thinking in Java, which is ideal for people who are not yet familiar with Java but have a basic understanding of an object-oriented language (such as C++), continues the previous version’s thoughtful approach to learning Java inside and out, while also speeding it up by explaining some of Java’s newest features. This comprehensive tutorial covers the many nooks and crannies of a language that has a significant say in the world of programming.

The most striking feature of the book is its careful and extremely thorough treatment of Java, with particular emphasis on object-oriented design. For example, ten pages of sample code show all available operators. Some of the best considerations about objects are in this book, including when to use composition over inheritance.

The esoteric details of Java in connection with the definition of classes are thoroughly described. The material on interfaces, inner classes and designing for reuse will delight any practitioner. Each section also contains sample exercises that will allow you to test and extend your Java knowledge.
