创建一个拼音类PinYin,需要一个 pinyin4j-2.5.0.jar 包

package com.demo.test;import java.util.HashMap;import net.sourceforge.pinyin4j.PinyinHelper;import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;public class PinYin {	/**     * 汉字转为拼音     * @param chinese     * @return     */    public static String ToPinyin(String chinese){                  String pinyinStr = "";         char[] newChar = chinese.toCharArray();         HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();          defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);          defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);          for (int i = 0; i < newChar.length; i++) {              if (newChar[i] > 128) {                  try {                      pinyinStr += PinyinHelper.toHanyuPinyinStringArray(newChar[i], defaultFormat)[0];                  } catch (BadHanyuPinyinOutputFormatCombination e) {                      e.printStackTrace();                  }              }else{                  pinyinStr += newChar[i];              }          }          return pinyinStr;      }      //测试一下方法    public static void main(String[] args) {//		String name = "好人";//		String name2 = ToPinyin(name);//		System.out.println(name2);    	HashMap
   
     map = new HashMap
    
     ();    	map.put("1", "2589");//    	String num = "13565";    	if (map.containsKey("2")) {			System.out.println("该字符串包含2这个数字");		}else {			System.out.println("该字符串不包含2这个数字");		}	}}
