内容简介
Scala是一门以Java虚拟机（JVM）为目标运行环境并将面向对象和函数式编程语言的最佳特性结合在一起的编程语言。你可以使用Scala编写出更加精简的程序，同时充分利用并发的威力。由于Scala运行于JVM之上，因此它可以访问任何Java类库并且与Java框架进行互操作。本书从实用角度出发，给出了一份快速的、基于代码的入门指南。Horstmann以“博客文章大小”的篇幅介绍了Scala的概念，让你可以快速地掌握和应用。实际上手的操作，清晰定义的能力层次，从初级到专家级，全程指导。本书适合有一定的Java编程经验、对Scala感兴趣，并希望尽快掌握Scala核心概念和用法的开发者阅读。
