多线程的学习，在一个程序中，这些独立运行的程序片断叫作“线程”（Thread），利用它编程的概念就叫作“多线程处理”。多线程处理一个常见的例子就是用户界面。利用线程，用户可按下一个按钮，然后程序会立即作出响应，而不是让用户等待程序完成了当前任务以后才开始响应。

-Multithreaded learning, in a program, these stand-alone program fragment called " thread"　(Thread), use it to programming concepts is called " multithreading."　Multithreading A common example is the user interface. The use of threads, the user can press a button, and then the program will respond immediately, rather than allowing users to wait for completion of the current task began after the response.
