Why Doesn't a PriorityQueue Iterator Guarantee Ordered Traversal?

Why Does the PriorityQueue Iterator Not Traverse Data in Order?

According to the Java Docs, the iterator used in the PriorityQueue's iterator() method does not guarantee the traversal of elements in any particular order. This is a result of the underlying data structure, a binary heap, not supporting such traversal.

A binary heap maintains elements in a partially ordered manner, with the smallest element located at the root. Removing the root element triggers a reordering of the heap to place the next smallest element at the root. This dynamic ordering process prevents efficient ordered traversal, hence the lack of such an algorithm in Java.
