Returning Futures

[vale meteor]

Hello, I am using Futures to return promises of results of a thread. But is it possible to 'fork' the execution of the function to execute a snippet of code just after finishing the thread? Here's the idea of the code.

public Future invoke_async(Map<Object, Object> params) {
  Funtion <Map<Object,Object>, Object> action = foo.getAction();
  Callable<Object> callable = () -> action.apply(params);
  ExecutorService executorService = Executors.newSingleThreadExecutor();
  Future future = executorService.submit(callable);
  //Here I would run a snippet of code after finishing the thread
  return future;
}```

Detected code, here are some useful tools:

Formatted code

public Future invoke_async(Map<Object, Object> params) {
  Funtion<Map<Object, Object>, Object> action = foo.getAction();
  Callable<Object> callable = () -> action.apply(params);
  ExecutorService executorService = Executors.newSingleThreadExecutor();
  Future future = executorService.submit(callable);
  //Here I would run a snippet of code after finishing the thread
  return future;
}

execution of the thread, without blocking the main thread?

2 ways

one is to use CompletableFuture and its .then, which just chains some code

the other is to .join the futures and just run something afterwards

3rd secret way is to use a StructuredTaskScope

but that relies on a preview feature
