新手求指教，这该怎么解啊？

package bag;
import java.util.Scanner;
public class ZhuanHanZi {
//
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner input = new Scanner(System.in);
System.out.println("输入你的数字：");
String[] str=
{"拾","佰","仟","万","拾","佰","仟","亿"};
String a= input.nextLine();
String result =getChinese(a);
int n=Integer.parseInt(result);
if (result.length()<=1)
System.out.println(result+"元整");
else
for(int j=0;j<n;j++){
char m=result.charAt(j);
System.out.print(""+m+""+str[n-j]);
}
input.close();
}
public static String getChinese(String str){
StringBuilder sb= new StringBuilder();
for(int i = 0; i < str.length(); i++){
char c = str.charAt(i);
switch(c){
case '0':sb.append("零");break;
case '1':sb.append("壹");break;
case '2':sb.append("贰");break;
case '3':sb.append("叁");break;
case '4':sb.append("肆");break;
case '5':sb.append("伍");break;
case '6':sb.append("陆");break;
case '7':sb.append("柒");break;
case '8':sb.append("捌");break;
case '9':sb.append("玖");break;

default :sb.append(c);
}
}
return sb.toString();
}
}
如果有更好的方法换算钱币的话，感谢提供

只是做了一些简单的打印，还有如超过亿元、中间有多个零时怎么处理。这些都没做，你自己看看吧。
