This chapter includes 14 problems that involve Java concurrency. We will start with several fundamental problems about thread life cycles and object- and class-level locking. We then continue with a bunch of problems about thread pools in Java including the JDK 8 work-stealing thread pool. After that, we have problems dedicated to Callable and Future. Then, we dedicate several problems to Java synchronizers (for example, barrier, semaphore, and exchanger). By the end of this chapter, you should be familiar with the main coordinates of Java concurrency and be ready to continue with a set of advanced problems.

Overview of this book
The super-fast evolution of the JDK between versions 8 and 12 has increased the learning curve of modern Java, therefore has increased the time needed for placing developers in the Plateau of Productivity. Its new features and concepts can be adopted to solve a variety of modern-day problems. This book enables you to adopt an objective approach to common problems by explaining the correct practices and decisions with respect to complexity, performance, readability, and more.
Java Coding Problems will help you complete your daily tasks and meet deadlines. You can count on the 300+ applications containing 1,000+ examples in this book to cover the common and fundamental areas of interest: strings, numbers, arrays, collections, data structures, date and time, immutability, type inference, Optional, Java I/O, Java Reflection, functional programming, concurrency and the HTTP Client API. Put your skills on steroids with problems that have been carefully crafted to highlight and cover the core knowledge that is accessed in daily work. In other words (no matter if your task is easy, medium or complex) having this knowledge under your tool belt is a must, not an option.
By the end of this book, you will have gained a strong understanding of Java concepts and have the confidence to develop and choose the right solutions to your problems.
