When this button is clicked it calls the saveTransaction() function that is within the PosDAO class, it passes to this function an ArrayList of salesdetails object, this list contains the data entered into the jTable which is the products and qty being sold.Write the saveTransaction function. You are to loop through the items and get the total sales, next you are to insert the current date and the total sales into the sales table. Reminder that the sales table SalesNumber field is set to AUTO-INCREMENT, hence the reason for only entering the total sales and current date in sales table.arrow_forward

The CityDB database will have a table named City, with the following columns: CityName & Population. Their Data Types: CHAR(50) Primary Key & DOUBLE. The CityName column stores the name of a city, and the Population column stores the population of that city. After you run the CreateCityDB.java program, the City table will contain 20 rows with various cities and their populations. Next, create an application that connects to the CityDB database and allows the user to select any of the following operations: Sort the list of cities by population, in ascending order. Sort the list of cities by population, in descending order. Sort the list of cities by name. Get the total population of all the cities. Get the average population of all the cities. Get the highest population. Get the lowest population.
