The following program AverageTest calculates and prints the average of all elements of an int array. Write a generic version of findAverage(... ) method so that the arguments could be of any type rather than restricted to int type. Write the necessary additional codes in the main() method to test the generic version of findAverage (...) method.

class AverageTest

{

public double findAverage( int [ ] sales)

{ int numSales = 0; double total = 0.0; // Calculate the total sales. for (int i = 0; i < 6; i++) total += sales[ i]; return total/6;

} };
