java实现汉字转为拼音

java实现汉字转为拼音：

1.需要导入pinyin4j.jar

package com.loo.pinyin;

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.HanyuPinyinVCharType;

import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;

public class ChineseToEnglish {

    // 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();

    }

    public static void main(String[] args) {

        System.out.println(getPingYin("鹿伟伟"));

        System.out.println(getPinYinHeadChar("鹿伟伟"));

        System.out.println(getCnASCII("鹿伟伟"));

    }

}

执行结果：
