Reactive programming in Java

" summary

Covers Java’s reactive-streams support (Java 9 Flow API) and RxJava types (Flowable/Observable) implementing backpressure. Uses a temperature-sensor demo that emits one reading per second, fails ~1-in-10 and completes after three values; shows building a Subscription that requests N items, uses an Executor to change threads to avoid stack overflow, inserts a Processor to convert Fahrenheit to Celsius, and merges city streams — demonstrating the examples run and fail as designed.
