Books for Intermediate/Advanced Programmer
Java Performance: The Definite Guide by Scott Oaks
Some of the most advantageous elements of the Java programming language include garbage collection, JVM, and performance optimization. The Definite Guide to Java Performance addresses all three of these Java topics in a straightforward yet effective manner. Java Performance: The Definitive Guide instructs readers on how to maximise Java threading and synchronisation performance capabilities, increase Java-driven database application performance, deal with performance difficulties in Java EE and Java SE APIs, and much more.
This book will also show you how to take heap dumps and histograms in Java, and then introduce you to numerous techniques to reduce your heap memory footprint.
It also includes a section on JDBC and JPA performance. The key point is that it tells you how selecting the appropriate JDBC / JPA methods may greatly exceed the benefits of SQL query optimization.
Similarly, it contains an entire chapter dedicated to describing multi-threading difficulties, hazards, and the impact on performance. It covers advanced concepts such as ForkJoinPool and Java 8 Streams.
Head First Design Patterns by Elisabeth Freeman and Kathy Sierra
A solid understanding of OOP and design patterns is required for creating flawless Java programmes. Head First Design Patterns is one of the best books for developing that specific grasp of the Java programming language. Head First Design Patterns addresses numerous frequently asked concerns about Java, such as why composition is superior to inheritance and how to modify a class runtime behaviour without disturbing the already tried and proven code.
The most recent edition of Head First Design Patterns has been updated for Java 8. In contrast to previous publications that use a text-based approach, Head First Design Patterns uses a visually rich style that makes learning faster and more efficient.
Effective Java by Joshua Bloch
This is not a book for a total newbie, but it is must read for any Java developer. You can tell it was written by an expert with a solid practical background since it discusses the broad themes and the nuances. This book is useful if you wish to grasp the underlying processes and gain a sense of how and why things are organised the way they are. Each chapter has “items” with loads of practical advice and a good explanation of the most recent Java features. It will teach you how to write good code.
You will not complete your shift from Java developer to advanced Java developer if you have not read this masterpiece. Because of the substance, clarity, message, and style, this is the most recommended book for senior Java developers.
Java - The Complete Reference by Herbert Schildt
You probably won’t start learning Java from the very beginning with this book, but you will refer to it at some point because it is a well-structured, fully-featured source on Java programming with examples from real-world programming.

If you are an intermediate or expert level Java programmer looking for a “back to the fundamentals” approach, this book is for you. It is a well-structured and comprehensive source on Java programming.
Clean Code by Robert C Martin
Clean Code is a famous Java programming book that teaches readers how to write better code. The clean Code is split into three parts. The first part discusses clean coding patterns, techniques, and concepts. The second section discusses a number of case examples of increasing complexity. Each of these is an exercise in code cleanup. The Clean Code’s third and final component is a single chapter that includes a collection of unwritten rules acquired while developing the case studies discussed in the previous section.
This book will teach you how to tell the difference between good and terrible code, as well as the fundamental concepts of producing clean, legible code that adheres to best practices.
