How to remove the element with Iterators

Question

I have a programm like this
Vector ts = new Vector();
ts.add("abc"); ts.add("abd");
Iterator it = ts.iterator();
ts.remove("abc");
it.remove();
while(it.hasNext())
{ System.out.println("val = " + it.next()); }
What is the problem if I use remove with iterator. It is giving the error java.lang.IllegalStateException. Can somebody tell me what is wrong with this.

Answer 1

You can only use Iterator#remove() inside the Iterator loop (thus, after setting the cursor to the element using Iterator#next()).
Also see the API doc: http://java.sun.com/javase/6/docs/api/java/util/Iterator.html
What exactly do you want to do after all?
