Book Description
Updated with the latest Maven coordinates,Java programming features,and API changes,this book is your guide to solving problems in writing asynchronous and event-based programs
RxJava is not just a popular library for building asynchronous and event-based applications; it also enables you to create a cleaner and more readable code base. In this book,you’ll cover the core fundamentals of reactive programming and learn how to design and implement reactive libraries and applications.
Learning RxJava will help you understand how reactive programming works and guide you in writing your first example in reactive code. You’ll get to grips with the workings of Observable and Subscriber,and see how they are used in different contexts using real-world use cases. The book will also take you through multicasting and caching to help prevent redundant work with multiple Observers. You’ll then learn how to create your own RxJava operators by: reusing reactive logic. As you advance,you’ll explore effective tools and libraries to test and debug RxJava code. Finally,you’ll delve into RxAndroid extensions and use Kotlin features to streamline your Android apps.
By the end of this book,you’ll become proficient in writing reactive code in Java and Kotlin to build concurrent applications,including Android applications.
What you will learn
Discover different ways to create Observables,Observers,and Subscribers
Multicast in order to push data to multiple destinations and cache and replay them
Express RxJava idiomatically with the help of Kotlin features such as extension functions and data classes
Become familiar with various operators available in RxJava to perform common transformations and tasks
Explore RxJava’s reactive types,including Flowable,Single,Maybe,and Completable
Demystify Observables and how they express data and events as sequences
