servlet入门问题，超级简单！
下面是一段最简单的servlet结构，俺是刚刚接触，怎么具体内容要写在异常里呀？

import   java.io.*;
import   javax.servlet.*;
import   javax.servlet.http.*;
public   class   ServletTemplate   extends   HttpServlet   {
public   void   doGet(HttpServletRequest   request,
HttpServletResponse   response)
throws   ServletException,   IOException   {
//   Use   "request "   to   read   incoming   HTTP   headers
//   (e.g.,   cookies)   and   query   data   from   HTML   forms.
//   Use   "response "   to   specify   the   HTTP   response   status
//   code   and   headers   (e.g.,   the   content   type,   cookies).
PrintWriter   out   =   response.getWriter();
//   Use   "out "   to   send   content   to   browser.
}
}

楼主什么意思？

throws ServletException, IOException 并不代码是写在异常里。

而是表示doGet方法有可能会抛出ServletException、IOException 2种异常
