I need help for this shopping cart application!
I'm currently learning how to create this shopping cart application. I'm very new to java and I have these questions to ask(Sorry if all of them are very stupid ones)
1) To make the application, I'm supposed to create many classes such as Product, Menu, Stockline, Stock and etc. I'm puzzled as to how all the classes could be combined and ran at the same time in ms dos? Is there a certain topic on this? Hope someone can tell me so I can go read up on it...
2) After creating a class, for e.g, Product, we were told to also create ProductTest. I do not understand the use of the ProductTest class. Why can't we just have the Product class?
I thank you all for taking time to read this. I've been learning java for a few weeks now, and still pretty puzzled about it. Hope I can get assistance from all you pros! Thanks again. :)
