13. Explain the life cycle of servlet
web 容器加载 servlet 并将其实例化后，servlet 生命周期开始，运行其 init() 方法进行 servlet 的初始化，请求到达时运行其 service 方法，service 方法自动派遣运行与请求对应的 doXXX 方法（doGet方法 doPost方法）等，当服务器决定将实例销毁的时候调用其 destroy 方法。
补充：servlet 与 CGI 的区别：
servlet 处于服务器进程中，它通过多线程的方式运行其 service 方法，一个实例可以服务于多个请求，并且其实例一般不会销毁，而 CGI 对每个请求都产生新的进程，服务完成后就销毁，所以效率上低于 servlet。
