write a java code to represent a sales class asfollows:

1- The Sales class contains the names ofsellers (strings) and the sales/seller/day (matrix of integers).Assume the number of sellers is set dynamically by the constructorand that the sellers work 6 days/week.

Example:

names/days	0	1	2	3	4	5
Ali	30	5	89	71	90	9
Ahmad	15	81	51	69	78	25
Omar	85	96	7	87	41	54

The class should contain the following methods:

- setSaleDetails, this method takes two arguments: the array ofsellers' names and their detailed sales as a matrix ofintegers.

- printSalesDetails. This method prints the sellers' names andtheir sales (as in the example)

- printTotalSalesPerSeller. This method prints the list of totalsales for each seller during the week

- getBestSeller . This method prints the name of the seller whoachieved the highest sales during the whole week.

- getBestSellerAtDay . This method takes an integer Day as anargument (from 0 - 5). and prints the name of the seller whoachieved the highest sales at this specific day.

----- You are asked to implement a tester class calledSalesTester which has the main and do the following:

- creates an object from class Sales with a specific number ofsales (example: 3)

- generates a random set of sales for each seller. Assumesales/day is integer and between 0 and 100.

- set the names of sellers and their sales (pass it to createdobject)

- calls all the methods of the class Sales for testing.
