Java实现“将数字⾦额转为⼤写中⽂⾦额”
前⾔：
输⼊数字⾦额参数，运⾏程序得到其对应的⼤写中⽂⾦额；例如：输⼊ 12.56，输出 12.56 ： 壹拾贰元伍⾓陆分；重点来了：本⼈亲测有效。
奉上代码：

15英文怎么读
// 判断输⼊的⾦额字符串是否符合要求
if (StringUtils.isBlank(str) || !str.matches("(-)?[\\d]*(.)?[\\d]*")) {

其中造句
}

return "零元";
}
// 判断⾦额数字中是否存在负号"-"
boolean flag = fal;
if(str.startsWith("-")){
// 标志位，标志此⾦额数字为负数
flag = true;
str = placeAll("-", "");
}
// 去掉⾦额数字中的逗号","
str = placeAll(",", "");
String integerStr;//整数部分数字
String decimalStr;//⼩数部分数字
// 初始化：分离整数部分和⼩数部分
if(str.indexOf(".")>0) {
integerStr = str.substring(0,str.indexOf("."));
decimalStr = str.substring(str.indexOf(".") + 1);
}el if(str.indexOf(".")==0) {

decimalStr = str.substring(1);
}el {

}
// beyond超出计算能⼒，直接返回

/ 整数部分数字
