Sample output goal:

Created arr1 object with the secondary constructor. ---->The elements of the array in arr1 object are: 1 2 3 4 5 6 ---->The product of all elements in the array is: 720

Created arr2 object with the default constructor. ---->The elements of the array in arr2 object are: 7 6 5 6 8 9 8 8 5 8 ---->The product of all elements in the array is: 232243200

---->The odd-indexed elements in arr2 object are: 1. 6 3. 6 5. 9 7. 8 9. 8

---->The smallest element in arr2 object is: 5

Enter a value to count the frequency of 8 8 appears 4 times.
