What are the differences between Timer and ScheduledExecutor in Java?

What are the differences between Timer and ScheduledExecutor in Java?

The main difference is that Timer is a legacy class, while ScheduledExecutorService is part of the concurrency framework introduced in Java 5.

Can you explain how Timer works?

Sure! Timer schedules tasks for future execution in a background thread. It can schedule tasks to run once or repeatedly.

What about ScheduledExecutor? How is it better?

ScheduledExecutor provides more flexibility, allowing you to schedule tasks with fixed-rate or fixed-delay execution, and it handles exceptions better.

Are there any performance differences between the two?

Yes, ScheduledExecutor is generally more efficient for managing multiple tasks, especially in a multi-threaded environment.

Which one should I use for a new project?

For new projects, it's recommended to use ScheduledExecutorService due to its enhanced features and better error handling.
