What are the main differences between using executors and threads in Java?
Executors provide a higher-level abstraction for managing threads, allowing for easier task scheduling and resource management. Threads are lower-level and require more manual management.
In what scenarios should I prefer using executors over threads?
You should prefer executors when you need to manage a large number of tasks, want to reuse threads, or need features like thread pooling and scheduling.
Can you explain how performance differs between executors and threads?
Generally, executors can improve performance by managing thread lifecycles and reducing overhead, especially in applications with many short-lived tasks.
Are there any downsides to using executors?
Yes, using executors can introduce some overhead and complexity, especially if you don't need the features they provide.
