The screen shown is used to enter the sales of the products into the sales and salesdetails tables. It utilizes the four depicted files ProductDAO.java, Product.java, PosDAO.java and Pos.java. The schema for the database is also depicted. The java code utilizes a jconnector to retrieve data from the database. When a product code is entered and then a quantity is entered, on the enter key pressed, the product code is sent to the getProduct(String ID) of a ProductDAO object and that function connects to the database and retrieves the data, placing it into a Product object and return this as Product object so that it can be placed into the Jtable of the PosGUI screen. Write the code for the getProduct(String ID) function located in the ProductDAO file. The code is equivalent to the prodid.
