Let’s get to the list.

What Book is Best for Learning Java?

Here are my top picks for the best java books to read this year:

1. Java: The Complete Reference.

This completely revised edition provides a complete reference to the Java programming language, including every new feature of Java SE 11. 

In addition, it features new coverage of:

  • Lambda expressions and closures; 
  • Autoboxing and unboxing; 
  • Multi-catch exception handling; 
  • Static methods in interfaces; 
  • Default methods in interfaces; 
  • The repeatable annotations feature (Java 5.0); 
  • The type annotations feature (Java 8); 
  • And much more.

As you know, Java is a key technology for enterprise solutions, whether it’s a desktop application or a server-side solution that needs to handle millions of transactions per minute. 

This book is the definitive guide written by Oracle Press and covers all the basics you need to begin developing Java applications.

It shows how to design, write, troubleshoot, run, and maintain high-performance Java programs. This book is primarily intended for programmers who are moving from another language to Java and who are comfortable with using compilers and interpreters. 

Experience with object-oriented programming (OOP) is also assumed.

2. Effective Java.

Effective Java™ is essential reading for anyone who wants to upgrade their Java programming skills to the level needed to quickly and smoothly take advantage of the enormous range of APIs available in the Java ecosystem today.

Java is a complex language because it supports multiple programming paradigms: object-oriented, imperative, functional, generic, and in (to come). 

This book offers specific best-practices advice for effective use of the language. It is addressed to anyone who programs in Java or is considering doing so — particularly programmers who have probable experience of coding in another language. 

The first part of the book addresses techniques that apply across all or most programming paradigms: individual statements, classes and interfaces, memory management, strings, and I/O. 

In the second part of the book, they deal with more specialized topics:

  • Modular programming. 
  • Networking. 
  • Concurrency. 
  • Design patterns 
  • Annotations. 
  • Generics. 
  • Enums. 
  • And maps.

3. Java 8 in Action.

This book moves on to explore one of the most serious weaknesses in Java, memory management. 

It demonstrates how Java 8 changes memory management so you can write code that will run more efficiently on multicore processors and will be easier to monitor when running on the Java Virtual Machine. 

Other important Java 8 topics covered in detail include functional-style programming, parallelism, binary file IO, and utility classes.

You’ll learn how Java 8 makes parallel programming easier with the new Fork/Join framework and then see how to take advantage of closures and the new Date and Time API. 

You’ll also find complete coverage of utility classes, a comprehensive analysis of the Nashorn Javascript engine, and a discussion of what Project Valhalla could mean for future versions of the language.

And, the lambdas chapter is not a tutorial on Clojure syntax but instead shows what you can do with Java 8 and why it’s useful. It’s important to have a good foundation in Java if you’re going to use lambda expressions effectively. 

If you feel like it’s worth attending two talks on lambdas, then read this book.

4. Java SE8: For the Really Impatient.

The Java programming language has been around for over 20 years and until now, it has been a static language. 

While that may not sound exciting, it has allowed fantastic advances in our understanding of how computers work. 

Still, we need to move forward, and features like closures and streams make Java one step closer to being a dynamic language. This book will provide a brief introduction to closures (lambdas) and the new streams framework. 

Lambda expressions are the most visible change in Java SE 8 but by no means the only one. 

They’re coupled with a new Streams API, which defines a set of operations on collections of elements that can be collected into streams. As the name implies, stream operations process elements progressively, potentially interleaved with other such operations. 

And, the goal is to provide you with convenient and flexible ways for computations to work over collections of values without taking explicit control.

5. Java Puzzlers.

Although the Java world grows more sophisticated and mature with every passing year, it still hides a host of insidious traps for the unwary programs.

This book presents 95 fiendish riddles that severely test a developer’s understanding of the Java programming language and its libraries.

These puzzles range from easy questions about commonly overlooked language features to serious problems with accepted solutions. Whether you’re a teacher, novice, or expert Java programmer, you’re likely to learn something new.

Packed with original and entertaining puzzles, Java Puzzlers is guaranteed to dazzle veteran programmers and make novice programmers wish they knew the language better.

6. Think Java.

Think Java is one of the few books that can claim to be truly introductory. 

And if you already know C or C++, then Think Java is probably a better choice than other popular introductory books – particularly other books in the Allen B. Downey series, such as Think Python.

It is an entertaining introduction to programming and computer science. In addition to being fun to read, it avoids dry and obscure language found in most computer books. 

It has numerous graphical illustrations–using the first letters of basic Java programming constructs to represent themselves. 

Therefore, when the word “class” appears in a drawing, it looks like a small “C”.

The book takes readers from the most basic concepts — variables, methods, loops — to writing complete applications, touching on such advanced topics as recursion, design patterns, inheritance, generic classes, and exceptions.

7. Core Java: An Integrated Approach.

It is very useful for the students of B.E. and MCA as well as professionals who already have worked in the Java field. 

This book is mostly based on fundamental concepts of Core Java so that students can create their foundation based on this book and we can put light on other concepts of Core Java by referring to this book meanwhile.

Summarizing all about it in a single sentence, this book is for anyone who wants to learn Java or wants to refresh his knowledge about Java. 

If you feel that the topics discussed in this book look suspiciously similar to any other programming language, then you are right: This book provides a smooth transition from your previous programming background to Java.

No other book covers the topic in such a systematic manner. And, fundamentally understanding concepts is extremely important to do well in your future interviews.

So, the more you learn, the better.

Conclusion.

Java must be the most popular programming language nowadays leaving python in the second position. I think the main reason is that there are millions of mobile applications being developed in java. 

Not only mobiles but it is used by almost all of the companies as their main technology platform for web applications development. 

Millions and thousands of companies are using java in their projects and it has become one of the highest-paid IT skills on the job market.

Here is a final summary of my top picks:

  • Java: The Complete Reference.
  • Effective Java.
  • Java 8 in Action.
  • Java SE8.
  • Java Puzzlers.
  • Think Java.
  • Core Java: An Integrated Approach.
