In what ways does it diverge? I have not read the book, but Bruce Eckel is known for not liking checked exceptions. Arne

In what ways does it diverge? Well, it's been a lot of years since I read it, so I had to go back and look at it again. I notice right away that he plunges into a discussion of inheritance with a section entitled "Inheritance: reusing the interface" in which he does not mention interfaces as such, but talks about base classes. Yes, concrete classes. That isn't thinking in Java at all. He comes around to interfaces as an afterthought, and presents them as something that "takes the concept of an abstract class one step further". This is backwards - the presentation should begin with interfaces and flow to concrete classes and instances. It's also not best-practice thinking. It comes so close - talking about types and /is-a/ vs. /has-a/ and all - but the notion of inheritance these days is secondary to the notion of interface implementation. You don't really think in Java most powerfully until you grok type analysis and programming to the interface, and IMHO introductory material should begin with that. Don't misconstrue. I don't hate the book. I just don't think it establishes the correct foundational viewpoint for the most effective Java. But it does come close, and most of what it says is sound. Like I say, /Thinking in Java/ is an OK beginner's book but it establishes some thought patterns that aren't really correct for Java programming, belying the book's name. -- Lew

The point of the question was to ask what to do instead, which, thank goodness, at least others in this thread have addressed. -- Lew

Of course I am, I saved him a lot of money. There is enough helpful people on the net and one just needs to ask. -- stirr your cofee properly
