Question
Write a generic class with a type parameter constrained to the Number class or any subclass of Number. The constructor should accept an array of such objects. The class should have methods that return the highest and lowest values in the array, the total of the elements, and the average value of all the elements.
I need help getting this code up and running with the code in the photo. If someone can help me out, I will appreciate it.
Can anyone help me. I need someone to make this program on the bottom work with the program in the photo. If you could can you please not have any scanner classes please.

This class keeps the sales figures for a number of
days in an array and provides methods for getting
the total and average sales, and the highest and
lowest amounts of sales.

/**

an array to the sales array.
