What are some use cases for Java Executors?

Java Executors are used for managing thread pools and executing tasks asynchronously. Common use cases include handling background tasks, managing concurrent requests in web applications, and scheduling periodic tasks.

Can you give me an example of using Executors in a web application?

Sure! In a web application, you might use an ExecutorService to handle incoming requests by delegating them to a pool of worker threads, allowing the server to process multiple requests simultaneously without blocking.

What are the benefits of using Executors over creating threads manually?

Using Executors simplifies thread management, improves resource utilization, and provides better control over task execution, such as scheduling and handling exceptions.

Are there any downsides to using Executors?

Yes, potential downsides include complexity in configuration, the need for careful management of thread lifecycles, and the risk of resource exhaustion if not properly handled.
