法2：
public class Test3 {
public static String translateMoney(int money) {
String total = "";//返回的字符串
String[] Money = { "零", "一", "二", "三", "四", "五", "六", "七", "八", "九"};
String[] Util = { " ","十", "百", "千", "万", "十", "百", "千", "亿"};
String strMoney = String.valueOf(money);//参数转字符串
String[] inMoney =strMoney.trim().split("");//参数转存到数组里
//此处数组为[, 9, 0, 0, 8, 7, 9]
for(int i=0;i<strMoney.length();i++){
String mon = Money[Integer.parseInt(inMoney[1+i])];
String util = Util[strMoney.length()-i-1];
total += (mon + util);
}
return total;
}
public static void main(String[] args) {
System.out.println(translateMoney(900879));
//九十零万零千八百七十九 有问题还需仔细处理
}
