今天講講如何把中文的漢字轉換為拼音首字母，如"中國"轉換為“zg”，這裡要用到一個開源jar包【pinyin4j】

<span style="font-size:14px;">import net.sourceforge.pinyin4j.PinyinHelper;

/**

public class WordToPinYin {

	public static String toPinyin(String str){
      String convert = "";
      for (int j = 0, int len = str.length(); j < len; j++) {
          char word = str.charAt(j);
          String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);
          if (pinyinArray != null) {
              convert += pinyinArray[0].charAt(0);
          } else {
              convert += word;
          }
      }
      return convert;
	}
}</span>
 

<span style="font-size:14px;">public static void main(String[] args){</span>

<span style="font-size:14px;">	String hzStr = "拼音";</span>

<span style="font-size:14px;">	System.out.printf(WordToPinYin.toPinyin(hzStr));</span>

<span style="font-size:14px;">}</span>
