This project contains the RX examples given in the book. There are far from being a complete introduction to reactive programming and RX-Java.
The examples are intended to be run directly from the main method of the different classes. So, once imported in your IDE, you should be able to run them. Alternatively, you can package the project and run them using:
java -cp target/reactive-programming-example-1.0-SNAPSHOT.jar FULLY_QUALIFIED_CLASS_NAME
For example:
java -cp target/reactive-programming-example-1.0-SNAPSHOT.jar io.vertx.book.rx.ObservableExample
Just run:
./mvnw package
On Windows, use:
./mvnw.bat package
