汉字转拼音

通过 pinyin4j 实现

public static void main(String[] args) {
		// TODO Auto-generated method stub
		String hanyu="大家好";
		HanyuPinyinOutputFormat outputFormat = new HanyuPinyinOutputFormat();
		 outputFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
		 outputFormat.setVCharType(HanyuPinyinVCharType.WITH_V);
		for(char hanyuchar:hanyu.toCharArray()){
		try {
			System.out.print(PinyinHelper.toHanyuPinyinStringArray(hanyuchar,outputFormat)[0]);
		} catch (BadHanyuPinyinOutputFormatCombination e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		}
		
	}
