If the processing thread needs to wait or needs the return value then `get()` or the other methods in the returned Future object such as `isDone()` can be used.

Pool size means the executor will keep four threads alive at any time. Having more threads in the pool means that more tasks can run concurrently. But a bigger pool only results in a speed gain if the PC can handle it! Allocating a pool that is uselessly large just wastes memory, so you need to find a good compromise: About the same to double the size of the number of cores in the computer makes sense.
