How do thread and ExecutorService compare in performance?

The performance comparison between threads and ExecutorService often depends on the specific use case. Generally, ExecutorService provides better resource management and can handle a larger number of tasks efficiently.

Can you explain why ExecutorService is more efficient?

ExecutorService manages a pool of threads, allowing for better reuse of threads and reducing the overhead of thread creation and destruction. This can lead to improved performance, especially in applications with many short-lived tasks.

Are there scenarios where using raw threads is better?

Yes, in scenarios where you need fine-grained control over thread management or when dealing with long-running tasks, using raw threads might be more appropriate.

What are the trade-offs between the two?

The trade-offs include complexity versus control. ExecutorService simplifies thread management but may abstract away some control, while raw threads offer more control but require more management effort.
