把汉字串转成对应的汉语拼音

1.需要引入的jar包：pinyin4j-2.5.0.jar

2.code如下：

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;

                System.out.println(cnFirstSpell(x));
                System.out.println(cnFullSpell(x));
        }
