How To Use

# Hello World!

A requisite "Hello World!" which creates an Observable from a list of Strings, subscribes to the Observable with a function that will print "Hello %!" for each string.

java

public static void hello(String... names) {
    Observable.toObservable(names).subscribe(new Action1<String>() {

        @Override
        public void call(String s) {
            System.out.println("Hello " + s + "!");
        }

    });
}

hello("Ben", "George");
Hello Ben!
Hello George!

Groovy

def hello(String[] names) {
    Observable.toObservable(names)
        .subscribe({ println "Hello " + it + "!"})
}

hello("Ben", "George")
Hello Ben!
Hello George!

Clojure

(defn hello
  [&rest]
  (-> (Observable/toObservable &rest)
    (.subscribe #(println (str "Hello " % "!")))))

=> (hello ["Ben" "George"])
Hello Ben!
Hello George!
