JAVA代码查错题(二)

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

ii[i] =Integer.parseInt(s[i]);

}

Arrays.sort(ii);

//asc

for(int i=0;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。

chineseMoneyPattern.put(“8″, HUNDRED_MILLION);

}
