7 books for Java Developers which promise a hike in Career- Worknrby

We have grown to think that Java is a difficult language and working with it requires a deep and huge amount of knowledge. But in reality, this is not how Java works. Of course, adequate knowledge is needed but there is no need to know abundance.

One cannot simply learn Java through practical implements, therefore, certain authors have come up with their books on Java. These books show solutions and tell how Java works. Though Java is a practical subject and when it comes to learning or getting hands on it, the clouds of difficulty cover one’s mind.

Making it easier for anyone who is preparing to walk through Java commands or has been working with Java commands from a long time, here are 7 books which can lead to Java hike in your career:

1. Effective Java 3rd generation:

Ruling the list with a crown is Effective Java 3rd Generation. This book comprises all the information of JDK 7, 8 and 9.

The book covers lessons on the following:

  • Functional Interfaces, Lambda expressions, method references, and streams
  • Some default and static methods in the interface
  • New library features- the optional interface, java.time, and the convenience factory methods for collection
  • Type interface- including the diamond operator for generic types
  • Annotation- SafeVarargas

2. Modern Java Recipes:

For all those people who like recipes, this is the book for you. The book has solutions for Java 8 and 9 problems. The book focuses on Java 8- use of Lambda Expressions, method references, and stream API.

Some recipes in the book are on:

  • Interface in java.util.function package
  • Conspiring Lambdas, method references, and streams
  • Stream Operations- for transforming and filtering data
  • Methods for executing concurrency and parallelism
  • Comparators and collectors for sorting and converting streaming data
  • Date and Time API- a replacement of Date and Calendar classes
  • Creating instances and extracting values from Java’s optional type
  • I/O capabilities- a new feature that supports functional streams

3. Java 9 modularity:

The book covers all the necessary aspects of Java 9. Author Paul Baker and Sander Mak have successfully provided the insight to Java 9.

Further, here is why you should go through this book:

  • To understand the Java module concepts
  • To know how to use JDK tools for modular development and migration
  • To master the patterns for building a modular application
  • To know the ways on how to migrate the existing applications and libraries to Java modules

4. Spring Microservices in action:

This book throws light upon the software world which is hiking its way to microservices architecture. Right from benefits, development, scalability, reliability, to methods of implementing microservices this book has got you all covered.

Why go for this?

  • Design principles about core microservices
  • Client-side resiliency with Spring, Hystrix, and Ribbon
  • Ways to deploy spring cloud applications
  • Tips on how to manage configuration with Spring Cloud Config
  • A guide on routing using Netflix Zuul

5. Clean Architecture:

The book focuses on ways to create a software architecture that can stand the test of time. This book removes misconceptions about design patterns and software architecture.

The architecture methods provided in the book are independent of UI, databases, frameworks and external agencies.

6. Spring in Action: 5th addition

Turns out to be an important book due to the introduction of reactive programming in spring. Spring works as an important part of Java, therefore, it is a must to go through this book. A thorough guide on how to code- build a database-backed web-based app step by step.

7. Kotlin in Action:

In 2017, Google declared Kotlin as an official language for Android App Development. Since then there has been a huge interest in learning this language. Though there are other JVM languages like Scala, Groovy and Closure which have been contributing to making of PolyGlot programmer yet it looks like fellow programmers cannot get enough of Kotlin.

What is inside?

  • Theory on domain Specific language
  • A fair explanation on functional programming on JVM’
  • The methods and results of combining Kotlin and Java
  • Tips on how to write clean and idiomatic code
