Can a `Stack` be used to implement a queue in Java?
No, a `Stack` is always for LIFO operations, so it cannot be used to implement a queue directly.
Thatâ€™s incorrect. Itâ€™s true that `Stack` is LIFO, but two stacks can be used to implement a FIFO queue.
Can you explain how two stacks can be used to simulate a queue?
