篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JAVA版数字转人民币大写-四位分割法（支持京兆）相关的知识，希望对你有一定的参考价值。
今天在网络上找JAVA版本的数字转人民币大写，找了几个版本，下载使用后都不怎么理想，或多或少存在点问题，另外一个原因就是出现了更大的金额兆（万亿），最后在前辈的基础上自己动手写了一个版本。
网络上找的版本在处理小数点前面部分基本都是一个整体考虑，这次自己写的版本则采用4位一个分割的方式处理，测试后的结果和WPS的EXCEL进行了对比，测试案例中都保持了一致，草稿版本，有问题欢迎指正。
测试过程中也发现了WPS的EXCEL对数字转人民币大写的最高限制,见图片黄色部分：
代码如下：
