JAVA编程题

1．现在输入n个数字，以逗号，分开；然后可选择升或者降序排序；按提交键就在另一页面显示按什么排序，结果为，提供reset
import java.util.*;
public class bycomma{
public static String[] splitStringByComma(String source){
    if(source==null||source.trim().equals(""))
     return null;
    StringTokenizer commaToker = new StringTokenizer(source,",");
    String[] result = new String[commaToker.countTokens()];
    int i=0;
    while(commaToker.hasMoreTokens()){
     result[i] = commaToker.nextToken();
     i++;
    }
    return result;
}
public static void main(String args[]){
String[] s = splitStringByComma("5,8,7,4,3,9,1");
int[] ii = new int[s.length];
for(int i = 0;i<s.length;i++){
ii[i] =Integer.parseInt(s[i]);
}
     Arrays.sort(ii);
     //asc
     for(int i=0;i<s.length;i++){
     System.out.println(ii[i]);
     }
     //desc
     for(int i=(s.length-1);i>=0;i--){
     System.out.println(ii[i]);
     }
}
}
2．金额转换，阿拉伯数字的金额转换成中国传统的形式如：（￥1011）－>（一千零一拾一元整）输出。
