Question 3 Used cars showrooms are places where used cars are displayed and sold. Write a method generateReport() that takes as a parameter a two-dimensional array named prices of size 7 x 5 that contains used car prices in which each row represents a day and each column represents a showroom. The method displays the average used car price for each showroom. In addition, it should display the showroom with the highest average car price. For example, if the main method for this program has prices array values as given below: public static void main(String[] args) { double [] [] prices = { } }; (3.0, 1.0, 1.0,7.0,5.0}, (1.5, 1.0,3.0, 1.0, 4.7}, {2.5,2.2,1.0,1.9,1.7}, (1.0, 1.0, 8.0, 2.2, 4.1}, {4.5,9.0, 8.0, 4.2,2.7}, {1.5, 1.0, 4.0, 4.2,2.3}, {6.5,4.5,9.7,2.9,3.7} generateReport (prices); Your generateReport() method should display the following output: Showroom 0 average used car price is 2.9285714285714284 Showroom 1 average used car price is 2.814285714285714 Showroom 2 average used car price is 4.957142857142857 Showroom 3 average used car price is 3.3428571428571425 Showroom 4 average used car price is 3.457142857142857 Showroom 2 has the highest average of 4.957142857142857 *You must use nested-loops to process the 2-dimensionals array

![Question 3
Used cars showrooms are places where used cars are displayed and sold. Write a method generateReport0
that takes as a parameter a two-dimensional array named prices of size 7 x 5 that contains used car prices in
which each row represents a day and each column represents a showroom. The method displays the average
used car price for each showroom. In addition, it should display the showroom with the highest average car
price.
For example, if the main method for this program has prices array values as given below:
public static void main(String[] args) {
double [] [] prices = {
(3.0, 1.0, 1.0,7.0,5.0},
{1.5, 1.0,3.0, 1.0, 4.7},
(2.5,2.2, 1.0,1.9,1.7},
(1.0, 1.0, 8.0,2.2, 4.1},
{4.5,9.0, 8.0, 4.2,2.7},
{1.5,1.0, 4.0, 4.2,2.3},
{6.5,4.5,9.7,2.9,3.7}
}
};
generateReport (prices);
Your generateReport() method should display the following output:
Showroom 0 average used car price is 2.9285714285714284
Showroom 1 average used car price is 2.814285714285714
Showroom 2 average used car price is 4.957142857142857
Showroom 3 average used car price is 3.3428571428571425
Showroom 4 average used car price is 3.457142857142857
Showroom 2 has the highest average of 4.957142857142857
