Priority Queue Priority Queue: The Priority Queue class is part of the java.util package and provides an efficient way to manage a collection of elements where each element has a priority. · Each element is inserted or deleted on the basis priority. · Higher priority >Lower priority · Same priority for [FCFS basis] (FCFS stands for .... First come First Serve ) Types of Priority Queue: Here’s some types of priority queue: 1. Ascending order Priority Queue 2.
