java从list中取出对象并获得其属性值的方法

package com.hb.test;

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;

public class Test {

    public static void main(String[] args) throws IllegalArgumentException,
            Exception {
        Person p1 = new Person("111", "aaa");
        Person p2 = new Person("222", "bbb");
        List list = new ArrayList();
        list.add(p1);
        list.add(p2);
        test(list);

    }

    public static void test(List list) throws Exception, IllegalAccessException {
        for (int i = 0; i < list.size(); i++) {
            Field[] fields = list.get(i).getClass().getDeclaredFields();
            Object oi = list.get(i);
            for (int j = 0; j < fields.length; j++) {
                if(!fields[j].isAccessible()){
                    fields[j].setAccessible(true);
                }

                System.out.println(fields[j].get(oi));
            }
        }
