This project is based on Gradle. If you have problems with importing it into IntelliJ IDEA, choose Java 8 during import and switch Java version to 9 after import. In the case of problems with compilation, update `gradle.properties` file. To build project, type: `./gradlew build`. To run the compiled project, type: `./gradlew run`.\n\nThe example implementations are examples from the Reactive Streams examples, as implementing one-off by-hand implemented Publishers/Subscribers is actually pretty hard to pull off - due to the restrictive [Specification](https://github.com/reactive-streams/reactive-streams-jvm) which governs how these implementations much behave.\n\nGit branches\n------------\n- `master` branch contains code snippets from presentation and exepriments\n- `presentation` branch contains code snippets for Java 8 shown during the presentation and empty project in Java 9 for live coding\n\nReferences\n----------\n- [Reactive Streams](http://www.reactive-streams.org/)\n- [Reactive Streams Specification](https://github.com/reactive-streams/reactive-streams-jvm)\n- [Reactive Streams TCK](https://github.com/reactive-streams/reactive-streams-jvm/tree/master/tck) (which all implementations *must* pass)\n\n- [Reactive Manifesto](https://www.reactivemanifesto.org/)\n- [Java 9 Reactive Streams](http://www.baeldung.com/java-9-reactive-streams)\n- [Reactive Programming with JDK 9 Flow API](https://community.oracle.com/docs/DOC-1006738)\n- [Flow Class JavaDoc](http://gee.cs.oswego.edu/dl/jsr166/dist/docs/java/util/concurrent/Flow.html)\n- [Java 9 new Features: Reactive Streams](https://aboullaite.me/java-9-new-features-reactive-streams/)\n- [Catching up RxJava with Java 9 Flow API](https://medium.com/@teachpendant/catching-up-rxjava-with-java-9-flow-api-b2e19ec40270)\n- [Java 9 (Part 5): Flow With the New Reactive Streams, First Look](https://dzone.com/articles/java-9-tutorial-flow-with-the-new-reactive-streams)\n- [Java 9 Flow API: asynchronous integer range source](http://akarnokd.blogspot.com/2017/03/java-9-flow-api-asynchronous-integer.html)\n- [Mastering own Reactive-Streams implementation.
