What is the answer? I have tried many queue.

Question about the task

Under discussion

I have tried blocking, deque and even stack...

Class description:
1. It implements the Queue interface.
2. It is used when working with threads.
3. Elements can only be taken from the queue after they have expired (their delay period has passed).
4. The head of the queue is the element that expires first.

Requirements:

The getExpectedClass method must not use the getDeclaredClasses method.
The getExpectedClass method must return the correct type.
The main method must call the getExpectedClass method.
The main method must display the returned class on the screen.

package com.codegym.task.task36.task3607; import java.util.Stack; /* Find the class by its description */ public class Solution { public static void main(String[] args) { System.out.println(getExpectedClass()); } public static Class getExpectedClass() { return Stack.class; } }

Finally, I found the DelayQueue, which I overlooked at documents.doc of DelayQueue

Simply look into Oracle docs of "Queue" interface and look into what classes implement this interface. class name says for itself.

Answer is here: Elements can only be taken from the queue after they have expired (their delay period has passed).
