Java 关于中文大写金额与阿拉伯数字 互相转换的问题（eclipse版）

Posted 2023-04-11

是要能相互转换的，不要只给数字转成中文大写的，最大数字范围达到万亿。
（输入“100002.1”时最好显示“拾万零贰点壹”，而不是“拾万零仟零佰零拾贰点壹”（要是写不出也没关系哦！））。请各位高手指点指点我这个菜鸟，多谢！！写的好的话会加分的！

参考技术B 最简单的...
public class T
public static void main(String[] args)
zhuanhuan(10001101);

private static void zhuanhuan(int s)
String[] c = "零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖" ;
String[] d = "元", "拾", "百", "仟", "万","拾万","百万","千万","亿" ;
String ss = s + "";//数字强行转换成字符串
StringBuffer buffer = new StringBuffer();
for (int i = 0; i < ss.length(); i++)
String k = ss.substring(i, i + 1);
int f = Integer.parseInt(k);
if (f == 0)
int u = Integer.parseInt(ss.substring(i - 1, i));
if (u != 0)
buffer.append(c[0]);

else
buffer.append(c[f]);
buffer.append(d[ss.length() - i - 1]);


System.out.println(buffer.toString());

参考技术C 这个得自己写函数了。呵呵。我有个VB的，晚上可以发给你看看。

JS处理部分写好了，那么是如何调用呢？往下看，同样简单：假设要在下面的div中显示大写金额，可以这样调用：

1	<div><b>已付金额总额(大写):</b><script language="javascript">document.write(Arabia_to_Chinese("3,060.00"));</script></div>

也就是把需要转换大写金额的小写数字输入在Arabia_to_Chinese()函数中，然后用javaScript的document.write方法显示在网页上。
