如下所示：

import net.sourceforge.pinyin4j.PinyinHelper;public class PinyinHelperUtil {  public static String getPinYinHeadChar(String str) {  StringBuilder convert = new StringBuilder();  for (int j = 0; j < str.length(); j++) {   char Word = str.charAt(j);   String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);   if (pinyinArray != null) {    convert.append(pinyinArray[0].charAt(0));   } else {    convert.append(word);   }  }  return convert.toString().toUpperCase(); } }
