PriorityQueue Class

The PriorityQueue class is a part of the Java Collections Framework and provides a way to manage elements based on their priority rather than their insertion order. Unlike a standard FIFO queue, a PriorityQueue orders its elements either according to their natural ordering (if they implement Comparable) or according to a custom Comparator provided at queue construction time. This makes PriorityQueue ideal for applications like task scheduling, where tasks with higher priority should be processed before those with lower priority.
