相关知识: 1.对于多选框获得的是一个字符串数组，在打印数组的时候要使用
Array.toString(arr),需要引入java.util.Arrays
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" import="java.util.Arrays"%>2.字符串对比使用
equals()函数
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" import ="java.util.Arrays"%>
