Servlet-習題案例

輸出當前的系統日期

 public class HelloServlet extends HttpServlet{
 
     protected void service(HttpServletRequest request, 
             HttpServletResponse response) throws ServletException, IOException {
 
         response.setContentType("text/html;charset=utf-8");//--------------設置響應類型及編碼格式
         PrintWriter out = response.getWriter();//--------------------------獲取response輸出流
         
         Date now = new Date();//-------------------------------------------獲取系統時間
         SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd");//--------設置時間格式
         
         out.println(sf.format(now));//-------------------------------------格式化並輸出時間
         out.close();//-----------------------------------------------------關閉流
         
         
     }
 }
