`abstract V`	`get()` Waits if necessary for the computation to complete, and then retrieves its result.
`abstract boolean`	`isCancelled()` Returns `true` if this task was cancelled before it completed normally.
`abstract boolean`	`isDone()` Returns `true` if this task completed.
`default V`	`resultNow()` Returns the computed result, without waiting.
