Java并发教程（Oracle官方资料）

Computer users take it for granted that their systems can do more than one thing at a time. They assume that they can continue to work in a word processor, while other applications download files, manage the print queue, and stream audio. Even a single application is often expected to do more than one thing at a time. For example, that streaming audio application must simultaneously read the digital audio off the network, decompress it, manage playback, and update its display. Even the word processor should always be ready to respond to keyboard and mouse events, no matter how busy it is reformatting text or updating the display. Software that can do such things is known as concurrent software.

The Java platform is designed from the ground up to support concurrent programming, with basic concurrency support in the Java programming language and the Java class libraries. Since version 5.0, the Java platform has also included high-level concurrency APIs. This lesson introduces the platform's basic concurrency support and summarizes some of the high-level APIs in the java.util.concurrentpackages.

 

计算机的使用者一直以为他们的计算机可以同时做很多事情。他们认为当其他的应用程序在下载文件，管理打印队列或者缓冲音频的时候他们可以继续在文字处理程序上工作。甚至对于单个应用程序，他们任然期待它能在在同一时间做很多事情。举个例子，一个流媒体播放程序必须能同时完成以下工作：从网络上读取数字音频，解压缩数字音频，管理播放和更新程序显示。甚至文字处理器也应该能在忙于重新格式化文本和刷新显示的情况下同时响应键盘和鼠标事件。这样的软件就被称为并发软件。 

通过Java语言和Java类库对于基础并发的支持，Java平台具有完全（from the ground up ）支持并发编程的能力。从JDK5.0起，Java平台还引入了高级并发APIs。这个课程不仅涵盖了Java平台基础并发内容，还对高级并发APIs有一定的阐述。
