java程序将汉字转成拼音

1.使用pinyin4j将汉字转成拼音，附件为pinyin4j的jar包

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 ChineseToPinYin {
	
	public static void main(String[] args) {  
        System.out.println(getPingYin("众志成铖 QQ：433647"));  
        System.out.println(getPinYinHeadChar("众志成铖 QQ：433647"));  
        System.out.println(getCnASCII("众志成铖 QQ：433647"));
        System.out.println(getFirstPinYinHeadChar("众志成铖 QQ：433647"));  
    }
	
	// 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;
	}

	// 返回第一个中文首字母大写
	public static String getFirstPinYinHeadChar(String str) {

		String convert = "";
		char word = str.charAt(0);
		String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(word);
		if (pinyinArray != null) {
			convert += pinyinArray[0].charAt(0);
		} else {
			convert += word;
		}
		return convert.toUpperCase();
	}

	// 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();
	}
