编写测试类：

package com.yealink.phonebook;

import com.yealink.phonebook.utils.PinyinUtils;

/**
 * Created by yl1794 on 2018/5/16.
 */
public class testPinYin {
    public static void main(String[] args){
        String test = "IT 娃哈哈 What 服务器工程师 shi";
        System.out.println(PinyinUtils.getPingYinAll(test));
        System.out.println(PinyinUtils.getPingYinAllUpper(test));
        System.out.println(PinyinUtils.getPingYinAllLower(test));
    }
}

测试结果如下：

IT wahaha What fuwuqigongchengshi shi
IT WHH What FWQGCS shi
IT whh What fwqgcs shi
