Okay, understood. And you are right, there hopefullt (and luckily, looking back at my code from former days :) always is a progress and you learn (baby-)step by (baby-)step.
However, I think that I chose to read a book in order to skip a few of these steps. Basically, I am trying to learn from other peoples mistakes and take advantage of their (superios) knowledge of a subject. So would it not be better instead of letting me go (although guided) through the same steps I would go through by myself just introducing me to the right way of doing it? Please don't get me wrong: I still think the approach to have an application evolve while you read the book is absolutely fine! However, I would have wished for examples that actually are being written and then used (with only minor modifications) till the end. About your example: Of course you are right. You cannot overload a newbie programmer's brainwith all the features of a language from the start. But you could show him ONE anonymous class. Then another in some other place. When he get's the hang of what it is and how and where to use it, you can use the classes he already wrote and introduce some more going "You have already seen how anonymous classes work - now here is another brilliant place where you can use it. If you don't get it, go back to chapter X and reread the part about anonymous classes." Thus you still have code that is the way it should be AND you get the newbie to understand how to program properly and use concepts where appropriate. On the other hand, showing the newbie how to write the (possibly complex) program without anonymous classes and then have him refactor the whole thing later to use anonymous classes he will not understand when to use and when not to use anonymous classes and he would have to go through the whole code again trying to understand it again. But again, that is just my opinion.
