Is there a Heap in java?

Question

I am porting a C++ library to Java and I need a heap data structure. Is there a standard implementation or will I need to do it myself?

Answer 1

In Java PriorityQueue can be used as a Heap.

Min Heap

PriorityQueue minHeap = new PriorityQueue<>();

Max Heap:

PriorityQueue maxHeap = new PriorityQueue<>(Comparator.reverseOrder());
