Sets?{Resolved}

For some reason when i create a Set multiple ways that contains the elements of a String[] that contains duplicates the Set ends up containing duplicates. :confused: This shouldnt be happening. Am i doing somthing wrong?

Code:

---

import java.util.*;
 
 public class T{
  public static void main(String args[]){

  String[] sarray={"1","4","4","5","4","3","6","4"};
 /*
  contains duplicates
  Collection l = new ArrayList(Arrays.asList(sarray));
  Set s = new TreeSet(l);

  for(Iterator i = s.iterator(); i.hasNext();){
      System.out.print(i.next());
  }
*/

 /*
  contains duplicates
  Set s = new TreeSet();
  for(int i = 0; i < sarray.length; i++){
    s.add(sarray[i]);
  }
  for(Iterator i = s.iterator(); i.hasNext();){
      System.out.print(i.next());
  }
 */
 
  /*
  contains duplicates
  Set s = new TreeSet();
  for(int i = 0; i < sarray.length; i++){
    s.add(sarray[i]);
  }
 
  Object[] o = s.toArray();
  for(int i = 0; i < o.length; i++){
    System.out.print(o[i]); 
  }
 */
  }   
 }

This is very strange.

Quote:

---

public interface Set
extends Collection

A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element.

Your code worked for me. But java is ver 1.3.0. I'm sure you're on 1.4.*

I tried the code and now it seems to work. :confused: Must have been that 5th molsen i had last night. :rolleyes:

In that case, I won't check it on 1.4.1_01.

I ran into some interesting results one time myself. It turned out that the solution was to reboot my Windows PC. Funny how that occasionally fixes things.

So tell me, had you rebooted and then it worked?

I would like to say that rebooting works all of the time to resolve a problem. Unfortunately it doesn't. At least in this case it did. :D
