java统计出现频率最高的3个单词，并输出出现次数

有如下字符串"In school and life, the most important driving force of work is the pleasure in work, the pleasure of working as a result, and the recognition of the social value of this result. "(用空格间隔) 编码实现，统计出现频率最高的3个单词，并输出出现次数 要求： 打印格式： the=5 of=4 and=2 (对于出现重复次数一样的，输出其中一个即可)

package com.sinosoft.system;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
