Is there an interface similar to Callable but with arguments?

Question

Is there an interface in Java similar to the Callable interface, that can accept an argument to its call method?

Like so:

public interface M

I just had the same issue. you can wrap any method to return a callable, and execute it's returned value. i.e.

 main {    
    Callable integerCallable = getIntegerCallable(400);
    Future future = executor.submit(integerCallable);
}

private Callable getIntegerCallable(int n) {
    return () -> {
            try {
                TimeUnit.SECONDS.sleep(n);
                return 123;
            } catch (InterruptedException e) {
                throw new IllegalStateException("task interrupted", e);
            }
        };
}
