面试数字转换

[pjkimi]

比如外面输入1234输出一千二百三十四，(当然外面可以随便输入什么数字)

import java.io.BufferedReader;

	public static void main(String[] args) throws IOException {

		try {

哦，上次我也问了这个问题，在网上的朋友帮助下解决了，程序如下：

import   java.text.DecimalFormat;
import java.io.*; 
import java.util.*;  

public   class   ChineseCurrency{   
        public   static   void   main(String[]   args)   { 
          try{ 
            System.out.print("请输入数值："); 
            BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); 
            String st=(String)br.readLine(); 
            double number=Double.parseDouble(st); 
            System.out.println(toChineseCurrency(new   Double(number))); 
             }catch(IOException e){}           
        }   
          
        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(); 
                        StringBuffer sb=new StringBuffer(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([兆万元])","$1").replaceAll("零[角分]","");   
                        return s;   
                }   else{   
                        throw   new   NumberFormatException();   
                }   
}
}
