In Java, thePriorityQueueclass is implemented as a priority heap. Heap is an important data structure in computer science. For a quick overview of heap,hereis a very good tutorial. 1. Simple Example The following examples shows the basic operations of PriorityQueue such as offer(), peek(), ...
item2,// return value > 0 if item1 has a higher priority than item2// return value === 0 if item1 has a priority equal to item2// return value < 0 if item2 has a higher priority than item1constructor(compareFn){this.#compareFn=compareFn;}add(item){this.#n++;this.#treeArr...
Java PriorityQueue is an unbounded Queue implementation that processes the items based on priorities. Custom ordering can be enforced with a Comparator.

This implementation is based on binaryheap libary with some changed design. PriorityQueue.new( [array/ordering] ) Create new priority queue. You can pass array to initialize queue with O(n) complexity (implemented with batchenq, see below). First argument also could be an ordering function ...
