Java ScheduledExecutorService Guide

ScheduledExecutorService in Java is used to execute tasks after a specified delay time or at a fixed time interval periodically. It makes executing timed tasks in the background very simple and can be used for tasks like timed, periodic, or delayed tasks. ScheduledExecutorService offers more flexibility and functionality compared to Timer and is safer and more efficient in a multi-threaded environment. It allows tasks to be executed, canceled when needed, or to retrieve the status of task execution.
