Overview of this book

<p>Java developers face many challenges such as managing data streams and increasing responsiveness and performance for their applications. This course will help you overcome these challenges in just seven steps. </p><p>This course will teach you the new programming paradigms of RxJava in just seven steps by building an e-commerce application. Each section will cover approximately 30 minutes of core hands-on training on reactive programming, followed by a practical assignment. You will work with functional programming, transformations, concurrency, error handling, and much more with reactive programming. </p><p>By the end of this course, you'll be proficient in using reactive principles to write high-performance and efficient event-based applications using asynchronous data streams with Java.</p>
