java汉字拼音首字母的获取解决方案

对于汉字首字母的拼音获取,可以使用
pinyin4j 2.5.0.jar  进行解决.封装了一个工具类
package com.util;

import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;

import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;
