Outdated java example in wiki

Outdated java example in wiki page :

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

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

    });
}

Change it to

public static void hello(String... names) {
        Observable.fromArray(names).subscribe(s -> System.out.println("Hello " + s));
    }
