Re: Vector Help!!

Maybe i should elaborate a little more

My application uses an Vector called stringArray. I am using a GUI to
access this Vector. I have 2 buttons. ("NEXT" and "PREVIOUS").
I would like to use these buttons to forwards or backwards through the
Vector Elements.
Now what i have below works. But once i push "Next" or "Previous" once
the applet just freezes and the record shown in the text area remains
the same. My code for this is below.

public void moveNext() {
try {
statLbl.setText("done");
ListIterator Lists = stringArray.listIterator();
//while (Lists.hasNext()) {
String nextElement = (String)Lists.next();
singleTextArea.setText(nextElement);
}
catch (ArrayIndexOutOfBoundsException f) {
System.out.println("No value at element");
statLbl.setText(" error ");
}
}

My QUESTION:

How would i use a "Class level variable" to store an instance of the
iterator in.?? ( as steve mentioned in the quote below)
I understand this would stop me creating the ListIterator every time i
press next or previous ( thus solving my problem hopefully)???????????

Can someone help me out here???????

are you trying to troll? you've already gotten your answer!

besides, in what sense does it "work" if as soon as you push a button it
freezes??
