How to insert long datatype in Priority Queue Java

Question

I want to store all long type integer to a priority queue, and I want to intialize the queue something like this

PriorityQueue<long> pQueue = new PriorityQueue<>();

Is there an alternative available in java collections to achieve something like this?

@tgdavies While I am no thought reader, a guess would be that it’s not so much that that question seems to be about `int`, not `long` (not even explicit) but more that that question is asking about transferring numbers from an *array*, which isn’t the issue here at all. While you and I make the necessary abstractions easily, we should not expect the same from everyone here. — Ole V.V., May 23 '22 at 06:56

Java doesn't allow primitive types in generics. You must use wrapper class like below.

PriorityQueue<Long> pQueue = new PriorityQueue<>();
