Chinese characters into pinyin

Creating a class pinyin PinYin, you need a pinyin4j-2.5.0.jar package

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<String, String> map = new HashMap<String, String>();
    	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");
		}
	}
