Mastering Concurrency Programming with Java 9 - Second Edition

By: Javier Fernández González

Overview of this book

Concurrency programming allows several large tasks to be divided into smaller sub-tasks, which are further processed as individual tasks that run in parallel. Java 9 includes a comprehensive API with lots of ready-to-use components for easily implementing powerful concurrency applications, but with high flexibility so you can adapt these components to your needs. The book starts with a full description of the design principles of concurrent applications and explains how to parallelize a sequential algorithm. You will then be introduced to Threads and Runnables, which are an integral part of Java 9's concurrency API. You will see how to use all the components of the Java concurrency API, from the basics to the most advanced techniques, and will implement them in powerful real-world concurrency applications. The book ends with a detailed description of the tools and techniques you can use to test a concurrent Java application, along with a brief insight into other concurrency mechanisms in JVM.

Threads in Java

Nowadays, computer users (and mobile and tablet users too) use different applications at the same time when they work with their computers. They can be writing a document with a word processor while they're reading the news or posting in a social network and listening to music. They can do all these things at the same time because modern operating systems support multiprocessing.

They can execute different tasks at the same time. But inside an application, you can also do different things at the same time. For example, if you're working with your word processor, you can save the file while you're adding text with bold style. You can do this because the modern programming languages used to write those applications allow programmers to create multiple execution threads inside an application. Each execution thread executes a different task so you can do different things at the same time.

Java implements execution threads using the Thread class. You can create an execution thread...
