Implement Job Scheduler with Delay Function Execution
Problem Implement a job scheduler which takes in a function f and an integer n, and calls f after n milliseconds. Solution Implementing a job scheduler that invokes a function f after n milliseconds can be achieved using threading and timers Code Java import java.util.concurrent.Executors; import java.util.concurrent.ScheduledExecutorService; import java.util.concurrent.TimeUnit; public class JobScheduler { private final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1); public void jobScheduler(Runnable f, int n) { scheduler.schedule(f, n, TimeUnit.MILLISECONDS); } public static void main(String[] args) { JobScheduler js = new JobScheduler(); Runnable exampleFunction = new Runnable() { @Override public void run() { System.out.println("Function called!"); } }; // Call exampleFunction after 2000 milliseconds (2 seconds) js.jobScheduler(exampleFunction, 2000); } } ...
