You're Using Java Queues Wrong (ArrayDeque)

🧩 *DESCRIPTION*

java.util.Stack has a performance flaw baked in since Java 1.0 — it extends Vector, so every operation is synchronized, even when you're on a single thread with no contention.

Enter ArrayDeque. It implements the Deque interface for O(1) push, pop, offer, and poll. Faster than Stack, faster than LinkedList, and contiguous in memory so your CPU cache actually helps.
