This series focuses more on learning the "Tao" of Java, that is, the interpretation of principles. The introduction of many grammatical concepts and their usage is not the focus of this book. Therefore, it will be easier for readers who have certain knowledge of programming languages ​​or have written Java code to read it.
"In-depth Understanding of Java Core Technology: Practical Notes for Java Engineers (Basics)" is not only suitable for readers to conduct systematic learning, but also suitable for readers to check for gaps and integrate the knowledge they have learned in the past.

Wonderful book review

This is an encyclopedia suitable for every Java engineer. The book covers a large number of details that are easily overlooked in our daily development, such as whether Java is passed by value or by reference, the thread safety issue of HashMap, and what is synchronization. Detailed issues such as blocking and asynchronous non-blocking can be explained in detail in this book. This book is suitable for students with certain development experience. I believe this book will help everyone write better code!

I have a point. When I usually learn Java, I always encounter some very basic problems, but I don’t seem to understand why. For example, whether Java is passed by reference or passed by value, then "In-depth Understanding of the Core of Java" Technology" book will give detailed answers. In addition, this book takes into account core Java knowledge points such as strings, collection framework, reflection, annotations, generics, etc. After reading this book carefully, I believe you will take another step on the road to becoming a Java god. A solid step.

Consolidate the foundation and technology. Every programmer who wants to go further must build a technical foundation. In-depth learning of any basic knowledge should not stop at memorizing, but use mathematical logical thinking. Learning from fundamental understanding. This book tells you the core principles behind Java technology with clear logic. This book is suitable for programmers who are building a technical foundation and in the growth stage.

Technology is developing too fast. We are always obsessed with all kinds of new "technical terms", but forget to consolidate the basic Java skills we commonly use. This book has accumulated Hollis's understanding and practice of Java core technology for many years, combined with exquisite code examples, to break down each knowledge point step by step. I believe that these useful information will benefit developers a lot, and are especially suitable for junior and intermediate engineers who want to advance to Java development.
