java 取汉语首大写字母

#1. 引包

<dependency>

    <groupId>com.belerweb</groupId>

    <artifactId>pinyin4j</artifactId>

    <version>2.5.0</version>

</dependency>

#2. 获取首字母

char c = PinyinHelper.toHanyuPinyinStringArray(你想获取的字符串.charAt(0))[0].charAt(0)

#3. 小写转大写

String str = String.valueOf(c);

str.toUpperCase()

以上方法实际使用中遇到了一个问题像长春，重庆等多音字不能正常显示，所以我该用了下面的方法
