JSP根据身份证号码计算生日 

 1 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

11 <% String id = "010020198810092211" ;
12     String birth = id.substring(6,14);
13 %>
14 <tr><td>010020198810092211</td><td><% out.print(birth); %></td></tr>
15 <% String id2 = "010020199009302211" ;
16     String birth2 = id2.substring(6,14);
17 %>
18 <tr><td>010020199009302211</td><td><% out.print(birth2); %></td></tr>
19 </table>
20 </body>

虽然写好了，感觉可弱智了，我的方案，呵呵

改进方案：

 1 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 2 <html>
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 5 <title>birthday</title>
 6 </head>
 7 
 8 <body>
 9 <table>
10 <tr><td>身份证</td><td>生日</td></tr>
11 <%!
12     public String birthJisuan(String id){
13     String birth = id.substring(6,14);
14     return birth;
15     }
16 %>
17 <tr><td>010020198810092211</td><td><%=birthJisuan("010020198810092211") %></td></tr>
18 <tr><td>010020199009302211</td><td><%=birthJisuan("010020199009302211") %></td></tr>
19 </table>
20 </body>
21 </html>

感觉稍稍进步了一点，呵呵
