人民币小写转大写

package test;

public class Www {

public static String toRMB(double money) {
char[] s1 = {'零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖'};
char[] s4 = {'分', '角', '元', '拾', '佰', '仟', '万', '拾', '佰', '仟', '亿', '拾', '佰', '仟', '万'};
//这两句是为后面转换做字典准备
String str = String.valueOf(Math.round(money * 100 + 0.00001));
//这是把参数money小数点后移2位,然后取整,即按照“分”为单位取整,再转为字符串型
String result = "";

for (int i = 0; i <str.length(); i++) {
int n = str.charAt(str.length() - 1 - i) - '0';
result = s1[n] + "" + s4[i] + result;
}
//这一段是按照转换出来的字符串按位取数字,再按照上面的字典将其逐位翻译成汉字
//如“2011”就翻译成“贰仟零佰壹拾壹元”,“98700432.10”就是“玖仟捌佰柒拾零万零仟肆佰叁拾贰元壹角零分”——注:这里的人民币大写汉字,貌似有错误,请查阅相关资料更正
//以上的翻译可以看出,和我们平时的认读有差别,于是以下就是在将那些应该纠正的地方手动剔除以下。上述两个例子最后得到的结果应该是“贰仟零壹拾壹元整”,“玖仟捌佰柒拾万零肆佰叁拾贰元壹角整”
result = result.replaceAll("零仟", "零");
result = result.replaceAll("零佰", "零");
result = result.replaceAll("零拾", "零");
result = result.replaceAll("零亿", "亿");
result = result.replaceAll("零万", "万");
result = result.replaceAll("零元", "元");
result = result.replaceAll("零角", "零");
