DelayQueue Java Explained: Timed Task Scheduling

DelayQueue is a delayed queue based on a priority queue, used to store elements that implement the Delayed interface. Elements in DelayQueue can only be taken out after their specified delay time has elapsed. DelayQueue is commonly used for task scheduling or executing timed tasks, enabling tasks to be executed based on a specified delay time. This allows for the implementation of tasks with delayed execution and timed task execution.
