An example of an AI chatbot conversation about Java thread pool best practices.
What are the best practices for using thread pools in Java?
Some best practices include defining the right pool size, using a cached thread pool for short-lived tasks, and handling rejected tasks properly.
How do I determine the right pool size?
A common approach is to use the formula: number of available processors * 2 for CPU-bound tasks, and for I/O-bound tasks, you can increase it based on the expected load.
What should I do if a task is rejected?
You can implement a RejectedExecutionHandler to handle rejected tasks, such as logging the error or retrying the task.
Can you explain the difference between fixed and cached thread pools?
A fixed thread pool has a set number of threads, while a cached thread pool creates new threads as needed and reuses them when available.
