在当今的软件开发领域，多线程编程是提高程序性能和响应能力的关键技术。Java 作为一种广泛使用的编程语言，提供了强大的多线程支持。Eclipse 作为一款功能强大的集成开发环境（IDE），为 Java 多线程编程提供了丰富的工具和便利。本文的目的是详细介绍 Eclipse 在 Java 多线程编程中的各种应用，包括代码开发、调试、性能分析等方面。范围涵盖了从基本的多线程概念到实际项目中的应用，旨在帮助开发者更好地利用 Eclipse 进行 Java 多线程编程。

今天下载了个eclipse的kapler版本，运行了个项目，用debug模式开启。 但是线程老是间歇性的停在 ThreadPoolExecutor$Worker.run()。上网搜了下，说是未捕捉异常导致的。可以在eclipse中修改下配置： 把"Suspend execution on uncaught exceptions" 把前面的勾去掉，然后就OK了

前言 Android开发中由于禁止在主线程中做网络请求，通常都需要使用线程对象来做异步请求操作，但是直接使用new Thread();创建新线程需要不停的申请系统资源，这些野生的线程缺乏统一管理，相互竞争占用过多系统资源；直接使用普通的线程做定期执行和线程中断等功能特别容易出错，为此 J.U.C类库里添加了功能强大的Executor框架，它能够为用户程序提供强大的线程池实现。使用JDK自带的线程...
