1、创建student.java类

package test;

import java.util.ArrayList;
import java.util.List;

public class student {
	private String name;
	private int age;
	private String sex;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public student() {
		super();
		// TODO Auto-generated constructor stub
	}
	public student(String name, int age, String sex) {
		super();
		this.name = name;
		this.age = age;
		this.sex = sex;
	}
	@Override
	public String toString() {
		return "students [name=" + name + ", age=" + age + ", sex=" + sex + "]";
	}

	public static List<student> getAll(){
		List<student> list = new ArrayList<student>();
		list.add(new student("zhansan", 20, "male"));
		list.add(new student("lili", 21, "female"));
		list.add(new student("wangwu", 19, "male"));
		return list;
	}
}

2、创建index.jsp

<%@ page language="java" import="java.util.*,test.student" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>hello jsp</title>
</head>
<body>
	<%
		List<student> list = student.getAll();
	%>

<table border="1" width="60%" align="center">
	<tr>
		<th>姓名</th>
		<th>年龄</th>
		<th>性别</th>
	</tr>

<%
	for(student stu : list){
%>
	<tr>
		<td><%=stu.getName() %></td>
		<td><%=stu.getAge() %></td>
		<td><%=stu.getSex() %></td>
	</tr>
<% 
	}
%>
</table>
	
</body>
</html>

3、在 index.jsp的 <%@ page language="java" import="java.util.*,test.student" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>这句中导入了路径为test.student的类

4、查看结果
