Create a class ArrayNumber to have following members:

private int number$[]$ array of size $7$

public void setElements$()$ method to store $5$ elements in array number

public void printElements$()$ method to print elements of array

public void calculateSum$()$ method to calculate sum of $5$ elements and store

it at $6$th location of the array number and at $7$th

location store total number of elements i$.$e $5$

public int printAverage$($ int totalSum, int totalNumber $)$ method to calculate

and print average of numbers.

Create a class TestArrayAverage having main method. Create an object of

ArrayNumber class. Call setElements$(),$ printElements$()$ to set and print

elements of array. Call calculateSum$()$ to calculate sum of elements in an

array. Call printAverage$()$ to calculate and print average by passing total sum

and total number of elements in an array.

Observe the exceptions occurring when wrong index numbers are passed and

value of total number as zero.
