why is the problem with this logic ?

why this code is not working

1 retreiving all the elements from the arraylist

2 i am spliting the string with white spaces and storing it in a array of string

3 and rest you can figure it out ...but what i m excepting is "yes" but i m getting "no"

void go ()
    {
        List l = new ArrayList();
        l.add("naved");
        l.add("aamir");

        String s = "naved";

//        if(l.contains(s))
//        {
//                     System.out.println("yes");
//        }


             String a = l.toString();
//             System.out.println(a);
             String[] su = a.split(" ");
             for(String str : su)
             {
                 if(s.equals(str))
                 {
                     System.out.println("yes");
                 }
                 else
                 {
                     System.out.println("no");
                 }
             }

    }

I'm pretty sure the answer would be obvious if you printed out "str" and "s" just before your If statement.

It's a pretty standard debugging technique: When your if statement isn't giving you what you expect, check to make sure you are REALLY comparing what you think you are.

In this case, you are not.
