I think it's reasonable to conclude that there is no widespread love for labeled breaks. But in practlce, this is astonishingly rare. If you have an interface with multiple abstract methods, then lambdas won't help you at all. When you look at your code, how many times do you produce an anonymous instance with more than one method? Many old Java idioms are no longer needed and new features such as modularization make you far more effective. Cheers, Cay I do define a lot of methods which take an interface and it is still convenient to be able to create an anonymous class as an argument in-situ during the invocation. Compare this behavior with the handling of suppressed exceptions in the try-with-resources statement.
Other than those mouse listeners :-? It will also tell you how to find out more about old-fashioned concepts that you might still see in legacy code, but won't dwell on them. There is nothing to be gained by learning and then un-learning that. Many old Java idioms are no longer required and new features like lambda expressions will increase programmer productivity, but navigating these changes can be challenging. I was expecting this part to be boring, but to my surprise the author did an excellent job of explaining Java core features in some ways I had not seen before. The first 50 pages or so covers the basics of variables, strings, and arrays. But there is still much left to explore. It also does not waste time explaining in tedious detail how a for loop works or anything like that.
And, perhaps most importantly, concurrency. When it comes to learning Java, this is just that book.

I thought this singular focus on the language worked really well. Many old Java idioms are no longer required and new features like lambda expressions will increase programmer productivity, but navigating these changes can be challenging. So to me, it's better a quick read reference type book, but it does have exercises at the end of each chapter to try. However, navigating these changes can be challenging. You are better off learning the good ways first, and then maybe, if you need to deal with legacy code, learn the ways of the past. In each and every chapter, Horstmann seems to have zeroed in on the most salient details of the topic at hand.
If I had to write all ten of them as top-level classes, so what? Concepts are presented in fully tested programs, complete with code walkthroughs, syntax shading, code highlighting and program outputs. Spend 24 hours with this book and you'll be writing your own Java programs, confident in your ability to use the language and learn more about it. Perfect introduction to Java for the experienced programmer. For example, where I am spending my sabbatical, there is a band of professors who insists that freshman students need to know how to process strings in C because they might need it for embedded programming. Runnable, Callable, Predicate and ActionListener.
Hi, I wrote this book from scratch instead of updating the 20-year old Core Java for a simple reason. When I was looking for a good book to learn from, there was not really a lot to choose from. Unfortunately, I do not have the time to respond personally to every report, but I do read them all and will post updates to this page. I mean, how many mouse listeners have you written in your life? Pretty soon the only ones who need to know about anonymous inner classes are the poor souls who study for certification exams. Everyone uses C++, and the class is universally available and far less error-prone. What happens if closing the resource throws an exception? Bug Report Form Please use this form to report any bugs that you find. I speak with some feeling here, because this is so often done wrong.
Horstmann—author of the classic two-volume Core Java—this indispensable tutorial offers a faster, easier pathway for learning modern Java. The author lays out best practice and things to avoid very cogently. Lambdas, streams, and the new concurrency libraries each get their own chapter. Cay Horstmann wrote:Or look at anonymous inner classes. The book covers only the core language. We customize your eBook by discreetly watermarking it with your name, making it uniquely yours. Then, if you find yourself with time on your hands and a penchant for archaeology or the need to study for an outdated certification exam , go ahead and investigate the mysteries of anonymous inner classes.
