What are the best practices for using ScheduledExecutorService in Java?

Some best practices include using a single ScheduledExecutorService instance, handling exceptions properly, and avoiding long-running tasks.

Why is it important to handle exceptions in ScheduledExecutorService?

Handling exceptions is crucial because unhandled exceptions can terminate the executor, leading to task failures and resource leaks.

Can you explain how to schedule a task with a fixed delay?

Sure! You can use the scheduleWithFixedDelay method, which takes a Runnable, an initial delay, and a delay between subsequent executions.

What happens if a scheduled task takes longer than the delay?

If a task takes longer than the specified delay, the next execution will wait until the current task completes before starting.
