用程序给出随便大小的10个数，序号为1-10，按从小到大顺序输出，并输出相应的序号

看到网上其他博友贴出来的这道题目的代码，运行却不能通过，遂自写程序。

package e5;

import java.util.*;
class MyObj{
 private int index;
 private int data;
 public MyObj(int index, int data) {
  this.index = index;
  this.data = data;
 }
 public int getIndex() {
  return index;
 }
 public void setIndex(int index) {
  this.index = index;
 }
 public int getData() {
  return data;
 }
 public void setData(int data) {
  this.data = data;
 }
}
public class RandomSort {
 @SuppressWarnings("unchecked")
 public static void showRandomBySort()
 {
  Random random = new Random();
  List list = new ArrayList();
  for(int n =1;n<=10;n++)
  {
   MyObj myObj = new MyObj(n,random.nextInt(1000));
   list.add(myObj);
  }
  Collections.sort(list,new Comparator(){
   public int compare(Object o1,Object o2)
   {
    MyObj obj1 = (MyObj) o1;
    MyObj obj2 = (MyObj) o2;
    return (obj1.getData()-obj2.getData());
   }
  });
  Iterator iter = list.iterator();
  System.out.println("序号：/t数值");
  while(iter.hasNext())
  {
   MyObj myObj = (MyObj)iter.next();
   
   System.out.println(myObj.getIndex()+"/t"+myObj.getData());
  }
  
}
 
      
 public static void main(String[] args) {
  showRandomBySort();
 }
}
