java的中文转拼音组件---pinyin4j

Pinyin4j是sourceforge.net上的一个开源项目，支持同一汉字有多个发音，还支持拼音的格式化输出，比如第几声之类的，同时支持简体中文、繁体中文转换为拼音。下面是其官方网址，其中提供了下载：

http://pinyin4j.sourceforge.net/

通常情况下，只需要用到其中的PinyinHelper类中的静态方法toHanyuPinyinStringArray就可以了，比如：

String[] pinyinArray =PinyinHelper.toHanyuPinyinStringArray('单');

for(int i = 0; i < pinyinArray.length; ++i)

{

         System.out.println(pinyinArray[i]);

}

就会输出：

dan1

chan2

shan4

这三种发音，后面的数字代表第几声。可以看到静态方法toHanyuPinyinStringArray返回的数据类型是一个String数组，它用来接收一个汉字的多个发音，如果toHanyuPinyinStringArray中的参数不是汉字，那么它会返回null
