Read the topic: REDISPLAY MENU BY USING DO... WHILE LOOP in Learn From Question page on eCampus PSUEDO-CODE (for the main) AND UML (for data type class) (psuedo-code and UML are analyzing and designing step that should be done before writing the code) -You have to provide the pseudo-code. It could be long, therefore, you can use word document to write the pseudo_code -Also, you should provide the UML of class data type SU2016PROJECT_SaleTransaction_yourLastName HOW TO DO THE LAB -Create the project name SU2016PROJECT_yourLastName then add the data type class name SU2016PROJECT_SaleTransaction_yourLastName and driver class SU2016PROJECT_SaleReport_yourLastName -The class SU2016PROJECT_SaleTransaction_yourLastName should have some data members to hold the information of each sale transaction, for example, transaction number (String), date (String), number of model A units sold (int), money of model A (double), number of model B sold (int), money of model B (double), paid amount (double, some transactions between reports this amount should be 0) -The data type class should have no-argument constructor, parameter constructor, method update if you want to set new values of all data members at the same time, and some methods that need for display the receipt or report on screen and for the line to write to the output files
