Efficient Data Handling with PriorityQueue and Custom Comparator in Java: Quick Tutorial

To use PriorityQueue in Java with a custom Comparator, you can create an instance of the Comparator interface and pass it to the PriorityQueue constructor.

In this example, we create a PriorityQueue of strings with a custom comparator that orders strings by their length. We add some strings to the queue and then print them in order using the poll() method. The CustomComparator class implements the Comparator interface and overrides the compare() method to provide a custom ordering.
