Imagine you are developing a system that requires scheduling of tasks, like sending notifications, at fixed-rate intervals. How would you implement this using concurrency utilities in Java?
- Use CachedThreadPoolExecutor: Dynamically adjust thread pool size to handle scheduling tasks efficiently.
- Use FixedThreadPoolExecutor: Allocate a fixed number of threads for scheduling tasks.
- Use ScheduledThreadPoolExecutor: Schedule tasks with fixed-rate intervals using scheduleAtFixedRate method.
- Use SingleThreadPoolExecutor: Execute tasks one by one with fixed-rate intervals to ensure sequential processing.
For scheduling tasks at fixed-rate intervals, the ScheduledThreadPoolExecutor is the most appropriate choice. It provides methods like scheduleAtFixedRate to achieve this functionality. CachedThreadPoolExecutor and SingleThreadPoolExecutor do not specialize in scheduling tasks, and using FixedThreadPoolExecutor is not optimal for scheduling.
