What are the best practices for using timers in Java?

When using timers in Java, it's important to consider thread safety, accuracy, and resource management. Use ScheduledExecutorService for better control.

Can you explain why ScheduledExecutorService is preferred over Timer?

ScheduledExecutorService is preferred because it handles exceptions better, allows for more flexible scheduling, and is more efficient in managing threads.

What are some common pitfalls to avoid when using timers?

Common pitfalls include not handling exceptions properly, using Timer in a single-threaded context, and not canceling tasks when they're no longer needed.

How can I ensure my timer tasks run at fixed intervals?

You can use the scheduleAtFixedRate method of ScheduledExecutorService to ensure tasks run at fixed intervals, even if previous tasks take longer.
