Question: chapter 2 in book and in examples

[meddle0x53]

There is a part of chapter 2 about lambdas - it introduces the new java8 syntax and creating lambdas/referencing methods. In the draft file, this content is in pages 2-13.

What I received starts like this:

2 
Why Observables? 

In this chapter, we are going to have an overview on the  Observer pattern, 
how it’s implemented and extended by RxJava, what an Observable  is, how Observables 
relate to Iterables.

[meddle0x53]

That sounds more like one of the sections of chapter 01, and it is not chapter 02, the outline I sent and they approved doesn't include anything like that in chapter 02...

It talks about Subjects, hot and cold Observables, and has examples such as this:

List<Integer> items = new ArrayList<Integer>();
items.add(1);
items.add(10);
items.add(100);
items.add(200);

Observable<Integer> observableString = Observable.from(items);

Subscription subscriptionPrint = observableString.subscribe(new Observer<Integer>() {
    @Override
    public void onCompleted() {
        System.out.println("Observable completed");
    }

    @Override
    public void onError(Throwable e) {
        System.out.println("Oh no! Something wrong happened!");
    }

    @Override
    public void onNext(Integer item) {
        System.out.println("Item is " + item);
    }
});

This I haven't found among the examples of this repository, so I'm confused. Feels like it is partially what's chapter 3 might be:

Chapter 3: Creating And Connecting Observables, Observers And Subjects – 15-20 pages
Description
We will get to know the basic building blocks of the RxJava library – we'll create RxJava Observables and Subscribers and interact with them; we'll introduce many of the Observable factory methods like 'from', 'just', 'empty'; we'll talk about 'hot' and 'cold' observables, 'blocking' and 'non-blocking' observables, 'connectable' observables and we'll subscribe to them. We will subscribe to these observables and unsubscribe from them, using a Subscription instance. At the end of the chapter, we'll play with and chain various Subject instances.

Are there other authors to the book or is the publisher restructuring the manuscript on their own?

[meddle0x53]

I'm the sole author - and this is chapter 03.

I guess they got it wrong, or they are editing it in some very strange way...

[akarnokd]

I assume you sent your chapter 2 about lambdas to the publisher before chapter 3, right?

[meddle0x53]

Yeah... in the beginning of the month... Maybe we should talk about these things in private...

Okay. Sent you a chat invitation via Google.
