java 拼音排序

将汉字转换为全拼  

public static String getPingYin(String src) {            char[] t1 = null;          t1 = src.toCharArray();          String[] t2 = new String[t1.length];          HanyuPinyinOutputFormat t3 = new HanyuPinyinOutputFormat();                    t3.setCaseType(HanyuPinyinCaseType.LOWERCASE);          t3.setToneType(HanyuPinyinToneType.WITHOUT_TONE);          t3.setVCharType(HanyuPinyinVCharType.WITH_V);          String t4 = "";          int t0 = t1.length;          try {              for (int i = 0; i < t0; i++) {                  // 判断是否为汉字字符                  if (java.lang.Character.toString(t1[i]).matches(                          "[//u4E00-//u9FA5]+")) {                      t2 = PinyinHelper.toHanyuPinyinStringArray(t1[i], t3);                      t4 += t2[0];                  } else                      t4 += java.lang.Character.toString(t1[i]);              }              // System.out.PRintln(t4);              return t4;          } catch (BadHanyuPinyinOutputFormatCombination e1) {              e1.printStackTrace();          }          return t4;      }   返回中文的首字母  
public static String getPinYinHeadChar(String str) {            String convert = "";          for (int j = 0; j < str.length(); j++) {              char Word = str.charAt(j);              String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);              if (pinyinArray != null) {                  convert += pinyinArray[0].charAt(0);              } else {                  convert += word;              }          }          return convert;      }  将字符串转移为ASCII码  
public static String getCnASCII(String cnStr) {          StringBuffer strBuf = new StringBuffer();          byte[] bGBK = cnStr.getBytes();          for (int i = 0; i < bGBK.length; i++) {              strBuf.append(Integer.toHexString(bGBK[i] & 0xff));          }          return strBuf.toString();      }  测试
 public static void main(String[] args) {          System.out.println(getPingYin("綦江QQ县"));          System.out.println(getPinYinHeadChar("綦江县"));          System.out.println(getCnASCII("綦江县"));      }  
需要添加pinyin4j-2.5.0.jar
