HOw is the Priority queue calling the comparator in this case?
I am not able to get at what time does the comparator sort the data inside the priority queue? Does it do at Queue creation? or on calling Poll()?

Please explain...I could not find the way even after debugging...!

If you debug again put a breakpoint in your compare method, you'll see that it's called for both the offer() and poll() methods.
They call fixup and fixDown respectively, those 2 do the comparing.
I agree. Here's the link:
