Write a program that implements the example described at the beginning of Section 9.6. Your program should shift the array’s elements from position x to position x – 1, as described in that section. (Move the value at position 1 to position 0; move the value at position 2 to position 1, and so on).

Start by creating two arrays,

double[] initialHours

and

double[] hours.

In its declaration initialize

initialHours

with the values

{8, 8, 6, 4, 7, 0, 0, 5},

but don’t initialize hours when you declare and instantiate it with its 31 elements. Instead, initialize

hours

after its creation by using

System.arraycopy

to copy all the values in

initialHours

into the first elements in hours. Then perform one down-shift operation, and load zero into the (new) highest element.
