Scala is a modern programming language for the Java Virtual Machine (JVM) that combines the best features of object-oriented and functional programming languages. Using Scala, you can write programs more concisely than in Java, as well as leverage the full power of concurrency. Since Scala runs on the JVM, it can access any Java library and is interoperable with Java frameworks. Scala for the Impatient concisely shows developers what Scala can do and how to do it. In this book, Cay Horstmann, the principal author of the international best-selling Core Java(t), offers a rapid, code-based introduction that's completely practical. Horstmann introduces Scala concepts and techniques in "blog-sized" chunks that you can quickly master and apply. Hands-on activities guide you through well-defined stages of competency, from basic to expert. Coverage includes * Getting started quickly with Scala's interpreter, syntax, tools, and unique idioms * Mastering core language features: functions, arrays, maps, tuples, packages, imports, exception handling, and more * Becoming familiar with object-oriented programming in Scala: classes, inheritance, and traits * Using Scala for real-world programming tasks: working with files, regular expressions, and XML * Working with higher-order functions and the powerful Scala collections library * Leveraging Scala's powerful pattern matching and case classes * Creating concurrent programs with Scala actors * Implementing domain-specific languages * Understanding the Scala type system * Applying advanced "power tools" such as annotations, implicits, and delimited continuations Scala is rapidly reaching a tipping point that will reshape the experience of programming. This book will help object-oriented programmers build on their existing skills, allowing them to immediately construct useful applications as they gradually master advanced programming techniques.
作者简介

Cay S. Horstmann is principal author of Core Java™, Volumes I and II, Eighth Edition (Prentice Hall, 2008), as well as a dozen other books for professional programmers and computer science students. He is a professor of computer science at San Jose State University and a Java Champion.
Key points of this chapter:
• Use an Array if the length is fixed, and an ArrayBuffer if the length can vary.
• Don’t use new when supplying initial values.
• Use () to access elements.
• Use for (elem <- arr) to traverse the elements.
• Use for (elem <- arr if . . . ) . . . yield . . . to transform into a new array.
• Scala and Java arrays are interoperable; with ArrayBuffer, use scala.collection.

Programming manuals are like fast foods, you never enjoy reading the book but sometimes that's the expediency. Scala is the official language for Spark, which I should have picked up between 2011 and 2013 if my physical status was much better. I'll ask my S...

前段时间学完了coursera上的“Functional Programming Principles in Scala”，现在正在自学“Principles of Reactive Programming”。和这两门课程的内容相比，这本书最大的问题就是对函数式编程的感念介绍太少，书中的内容大都是scala语法类库的堆砌。比如说对foldLeft、fold...

scala真是一种典型学院派的语言，后5章就看了隐式转换，看到implicit evidence就实在看不懂了。

Scala估计是这个世界上唯一的复杂度超过C++的语言。

只适合当字典用 最关键的类型系统太粗略了 想好好学Scala的话还是要读其他的书

写得很简洁，没有废话，相对于其他的scala语法书，这本书涵盖内容很广，却很薄，而且内容新，适合作为案边的语法工具书。
