HashCode ?

[praveenkumarvpk]

public static void main(String args[]) {    
        String elements[] = { "A", "B", "C", "D", "E" };
        Integer l[] = {1,2,68};
        Integer y=1;
        int d=0;
        for(int i=0;i<l.length;i++)
            System.out.println(l[i]);
 
        Set set = new HashSet(Arrays.asList(elements));
//        set.addAll(Arrays.asList(l));
        set.addAll(Arrays.asList(l));
        set.add(y);
        set.add(d);
    System.out.println(elements);
 
        Iterator itr=set.iterator();
 
    while(itr.hasNext())    {
        Object hs=itr.next();
        System.out.println("Value : "+hs+"\t Hash Code :"+hs.hashCode());
        //System.out.println("Value : "+itr.next()+" Hash Code :"+itr.hashCode());
        }
        Set set2 =((Set) ((HashSet) set).clone());
        System.out.println("Hash Code :"+set.hashCode());
        System.out.println("Hash Code :"+set2.hashCode());
        System.out.println(set2);    
      }    

This is my program...
So my problem is for every object there should be a uniq hasCode isn't it. But i'm getting some same hashCode for some different objects.
Like....
[Ljava.lang.Stri ng;@10b62c9
Value : 68 Hash Code :68
Value : 2 Hash Code :2
Value : D Hash Code :68
Value : A Hash Code :65
Value : 1 Hash Code :1
Value : C Hash Code :67
Value : B Hash Code :66
Value : 0 Hash Code :0
Value : E Hash Code :69
Hash Code :406
Hash Code :406
[D, 2, 68, A, C, 1, B, E, 0]


Help me out!

Hash codes need not be unique but if two hash codes are not equal you can be
sure that you're dealing with two different objects.
