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
     }         
}
