Answer 1

The first answer (by Nandkumar) is right, I'd also check the runtime error, caused by this lines:

while (litr.hasPrevious ())  
    {  
        Object obj3=litr.next ();  
        System.out.print (obj3+",");  
    }

That is: you check if your iterator has a "previous" item, then go for tne "next"? Probably not what you intended to do.

The "error" at compile time is only a warning, you can run your program after compilation, but the compiler is telling you that it found something strange in your code.
