What You Will Learn

• Discover what reactive programming is and how you can benefit from it
• Get to grips with the new functional features of Java 8 and some functional theory
• Create RxJava Observable instances from virtually any data source
• Transform, filter, and accumulate your data using various RxJava operators
• Combine multiple data sources in one dataset, using custom logic
• Write concurrent programs with ease, scheduling actions on various workers
• Learn about unit testing asynchronous RxJava logic
• Extend RxJava by writing your own operators and factory methods

In Detail

Whether you are a Java expert or at a beginner level, you'll benefit from this book, because it will teach you a brand new way of coding and thinking.

The book starts with an explanation of what reactive programming is, why it is so appealing, and how we can integrate it in to Java. It continues by introducing the new Java 8 syntax features, such as lambdas and function references, and some functional programming basics. From this point on, the book focuses on RxJava in depth. It goes through creating Observables, transforming, filtering, and combining them, and concurrency and testing to finish with extending the library itself.

This book is a definite tutorial in RxJava filled with a lot of well-described examples. It explains reactive programming concepts in plain and readable language, without scientific formulas and terms.
