What is the difference between `ExecutorService.submit()` and `ExecutorService.execute()` in Java?

Accepted Answer

The main difference between `ExecutorService.submit()` and `ExecutorService.execute()` in Java is that `execute()` accepts Runnable and returns void, while `submit()` accepts Runnable or Callable and returns a Future. This distinction allows for exception retrieval and result collection with `submit()`.
