```java

 Announcer announcer = new Announcer();

 // simple lambda subscriptions

 announcer.subscribe(String.class, str -> System.out.println("received string: " + str));

 announcer.subscribe(Number.class, n -> System.out.println("received number: " + n));

 announcer.subscribe(Integer.class, i -> System.out.println(i*2));

 // announce events

 announcer.announce("test string");

 announcer.announce(3);

  // custom listener and event objects

 MyListener listener = new MyListener();

 announcer.subscribe(AnEvent.class, listener::onTestEvent);

 announcer.announce(new AnEvent("some payload"));

 announcer.announce(new ASubEvent("some payload"));

 // unsubscribe

 Subscription subscription = announcer.subscribe(AnEvent.class, (evt) -> {})

 announcer.unsubscribe(subscription);
