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。
package test.format;
import java.text.NumberFormat;
import java.util.HashMap;
public class SimpleMoneyFormat {
  public static final String EMPTY = "";
  public static final String ZERO = "零";
  public static final String ONE = "壹";
  public static final String TWO = "贰";
  public static final String THREE = "叁";
  public static final String FOUR = "肆";
  public static final String FIVE = "伍";
  public static final String SIX = "陆";
  public static final String SEVEN = "柒";
  public static final String EIGHT = "捌";
  public static final String NINE = "玖";
