How to help Java decide on types?

Question

Java

There is a code:

listenForWhisper(socketManager.<MessagingUser>presenceChannel("dialog-" + dialog.getId()),
    WhisperEvent.EVENT_TYPING, TypingEvent.class);

listenForWhisper method:

public <T> SocketChannel listenForWhisper(SocketPresenceChannel<T> channel, String name,
                                          Class<? extends WhisperEvent<T>> event) {
        if (!channels.containsKey(channel.getName())) {
            channels.put(channel.getName(), channel);
        }
        return channel.listenForWhisper(name, event);
    }

As you can see, I have to explicitly specify the data type, which looks rather dubious. I can write like that, it’s not difficult for me, but what about the readability of such code?
Or is it better not to bring it up?
