Future type. I would use a standard array for this to help with output later rather

than a built$-$in java class. This time you will create an ExecutorService with a ThreadPool type

of newCachedThreadPool$()$ type. This will create threads as needed to meet the demand.

Next, the program should create $613$ sampleCallable objects and submit them for execution to

the ExecutorService object and, as you saw in part a$)$ it should store the results into the array

of Futures for later access.

Once again, the main method should iterate through the List of Futures but this time note that

an actual useful value IS being returned. It will be the Integer representing the square that

particular callable thread produced. I would suggest that you use a for loop to walk through the

array calling the get$()$ method on the Futures and printing out the results as they are received.

Be sure the output matches $($in terms of thread numbers$)$ the correct values.

Once again, when you get through the loop all threads will have produced their results.

shutdown$()$ the ExecutorService object, sleep for a couple of seconds and then end the

program. Help me with create appropiarte $.$ccp and $.$h for class and main
