人民币大小写转换问题
java代码如何把数字如1987.25元转化为壹仟玖佰捌拾柒元贰角伍分

[解决办法]
建立一个二维数组咯！然后讲大小写对应输入到二维数组当中，最后对这个float数字进行按位提取，分别提取万、千、百、十、元、角、分的各位，最后再组合成大写就可以了。
[解决办法]
这种小东西，还是自己动手写写的好吧。

have a try~

public static String toChineseCurrency(Object o) {
if(o instanceof Number) {
String s = new DecimalFormat( "#.00 ").format(o);
System.out.println(s);
s = s.replaceAll( "\\. ", " ");
char[] digit = { '零 ', '壹 ', '贰 ', '叁 ', '肆 ',
'伍 ', '陆 ', '柒 ', '捌 ', '玖 '};
String unit = "仟佰拾兆仟佰拾亿仟佰拾万仟佰拾元角分 ";
int l = unit.length();
StringBuilder sb = new StringBuilder(unit);
for(int i=s.length()-1; i> =0; i--)
sb = sb.insert(l-s.length()+i, digit[(s.charAt(i) - 0x30)]);
s = sb.substring(l-s.length(), l+s.length());
s = s.replaceAll( "零[拾佰仟] ", "零 ").
replaceAll( "零{2,} ", "零 ").
replaceAll( "零兆 ", "兆 ").
replaceAll( "零万 ", "万 ").
replaceAll( "零元 ", "元 ").
replaceAll( "零[角分] ", " ")
;
return s;
} else {
throw new NumberFormatException();
}
}

这个正解．(zephyr_cc())我支持．

这个blog里的有bug(http://blog.csdn.net/davis129/archive/2006/08/27/1127374.aspx)
我输入100035.53，输出（壹拾零叁拾伍圆伍角叁分）中间少了个万．应该是（壹拾万零叁拾伍圆伍角叁分）．

[解决办法]
yilinhust:
你的测试程序有问题,当输入1的时候程序会一直执行下去!因为在你第二个while后面你把输入流关闭了,所以读取金额抛异常!!
把:try{
in.close();

}catch(IOException e){

}
去掉就行!!!
