Master the principles and techniques of multithreaded programming with the Java 8 Concurrency API

Mastering Concurrency Programming with Java 8

About This Book

• Implement concurrent applications using the Java 8 Concurrency API and its new components
• Improve the performance of your applications or process more data at the same time, taking advantage of all of your resources.
• Construct real-world examples related to machine learning, data mining, image processing, and client/server environments

Who This Book Is For
If you are a competent Java developer with a good understanding of concurrency but have no knowledge of how to effectively implement concurrent programs or use streams to make processes more efficient, then this book is for you.

What You Will Learn

• Design concurrent applications by converting a sequential algorithm into a concurrent one
• Discover how to avoid all the possible problems you can get in concurrent algorithms
• Use the Executor framework to manage concurrent tasks without creating threads
• Extend and modify Executors to adapt their behavior to your needs
• Solve problems using the divide and conquer technique and the Fork/Join framework
• Process massive data sets with parallel streams and Map/Reduce implementation
• Control data-race conditions using concurrent data structures and synchronization mechanisms
• Test and monitor concurrent applications

In Detail
Concurrency programming allows several large tasks to be divided into smaller sub-tasks, which are further processed as individual tasks that run in parallel. All the sub-tasks are combined together once the required results are achieved; they are then merged to get the final output. The whole process is very complex. This process goes from the design of concurrent algorithms to the testing phase where concurrent applications need extra attention. Java includes a comprehensive API with a lot of ready-to-use components to implement powerful concurrency applications in an easy way, but with a high flexibility to adapt these components to your needs.

The book starts with a full description of design principles of concurrent applications and how to parallelize a sequential algorithm. We'll show you how to use all the components of the Java Concurrency API from basics to the most advanced techniques to implement them in powerful concurrency applications in Java.

You will be using real-world examples of complex algorithms related to machine learning, data mining, natural language processing, image processing in client / server environments. Next, you will learn how to use the most important components of the Java 8 Concurrency API: the Executor framework to execute multiple tasks in your applications, the phaser class to implement concurrent tasks divided into phases, and the Fork/Join framework to implement concurrent tasks that can be split into smaller problems (using the divide and conquer technique). Toward the end, we will cover the new inclusions in Java 8 API, the Map and Reduce model, and the Map and Collect model. The book will also teach you about the data structures and synchronization utilities to avoid data-race conditions and other critical problems. Finally, the book ends with a detailed description of the tools and techniques that you can use to test a Java concurrent application.

Style and approach
A complete guide implementing real-world examples with algorithms related to machine learning, data mining, and natural language processing in client/server environments. All the examples are explained in a step-by-step approach.

Invoke TDD principles for end-to-end application development with Java

About This Book

• Explore the most popular TDD tools and frameworks and become more proficient in building applications
• Create applications with better code design, fewer bugs, and higher test coverage, enabling you to get them to market quickly
• Implement test-driven programming methods into your development workflows

Who This Book Is For
If you're an experienced Java developer and want to implement more effective methods of programming systems and applications, then this book is for you.

What You Will Learn

• Explore the tools and frameworks required for effective TDD development
• Perform the Red-Green-Refactor process efficiently, the pillar around which all other TDD procedures are based
• Master effective unit testing in isolation from the rest of your code
• Design simple and easily maintainable codes by implementing different techniques
• Use mocking frameworks and techniques to easily write and quickly execute tests
• Develop an application to implement behaviour-driven development in conjunction with unit testing
• Enable and disable features using Feature Toggles

In Detail
Test-driven development (TDD) is a development approach that relies on a test-first procedure that emphasises writing a test before writing the necessary code, and then refactoring the code to optimize it.

The value of performing TDD with Java, one of the most established programming languages, is to improve the productivity of programmers, the maintainability and performance of code, and develop a deeper understanding of the language and how to employ it effectively.

Starting with the basics of TDD and reasons why its adoption is beneficial, this book will take you from the first steps of TDD with Java until you are confident enough to embrace the practice in your day-to-day routine.

You'll be guided through setting up tools, frameworks, and the environment you need, and will dive right in to hands-on exercises with the goal of mastering one practice, tool, or framework at a time. You'll learn about the Red-Green-Refactor procedure, how to write unit tests, and how to use them as executable documentation.

With this book you'll also discover how to design simple and easily maintainable code, work with mocks, utilise behaviour-driven development, refactor old legacy code, and release a half-finished feature to production with feature toggles.

You will finish this book with a deep understanding of the test-driven development methodology and the confidence to apply it to application programming with Java.

Style and approach
An easy-to-follow, hands-on guide to building applications through effective coding practices. This book covers practical examples by introducing different problems, each one designed as a learning exercise to help you understand each aspect of TDD.
