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.
