今天是练习了一下list的用法，Stud是自己定义的user类 ，

List<Stud> list=new ArrayList<Stud>();

Stud student=new Stud(rs.getString("name"),rs.getString("number"),rs.getString("xingbie"),rs.getString("xueyuan"));

System.out.println(rs.getString("name"));
System.out.println(rs.getString("number"));
System.out.println(rs.getString("xingbie"));
System.out.println(rs.getString("xueyuan"));
list.add(student);

　　　　 

  还有把list用request的setAttribute存入，request.setAttribute("list", list);再在jsp里面获取打印输出

<%@page import="java.util.ArrayList"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<c:forEach var="l" items="<%=list %>">

<tr style="text-align:center">
<td>${l.getNumber()}</td>
<td>${l.getName()}</td>
<td>${l.getXingbie()}</td>
<td>${l.getXueyuan()}</td>
<td>

<br>
</form></td>
</tr>
</c:forEach>
