My code is:

Set<String> windowsid = driver.getWindowHandles();
Iterator<String> iterate = windowsid.iterator();

while(iterate.hasNext()){
    System.out.println(iterate.next());
}

String mainwindow_id = iterate.next();
String tabbedwindow_id = iterate.next();

I get an error @ String mainwindow_id = iterate.next();

Stating the below, Line 45 is the one i have in quotes.
I have declared the Set as String

Please Help !

After the loop,

while(iterate.hasNext()){ 
    System.out.println(iterate.next()); 
} 

there are no elements left in the set to iterate. You iterated through all the windows and that’s why NoSuchElementException.

Can you explain a little bit about what you want to do?

If I understand you correctly, you dont need to use a loop. Since there are only two windows, you can just do ..

Set<String> windowsid = driver.getWindowHandles();
Iterator<String> iterate = windowsid.iterator();

String mainwindow_id = iterate.next();
String tabbedwindow_id = iterate.next();
