Java programming

Hello,
I am currently enrolled in an AP computer science class and i am having a bit of trouble with some of the assignments and our teacher refuses to help us saying that we need to figure it out on our own. I have basically no backround information when it comes to programmind and i was told that in this class you are taught from the beginning. We have recently been told to make a CashRegister class and a CashRegisterTester class to test the first class. I was able to make both classes without a problem but now i have to had a counter to the CashRegister class so that it keeps track of the total number of items in a sale and then add a tester for this in the CashRegisterTester class any help would be greatly appreciated. If you want to look at my classes just ask for it in a private message.
Thanks,

Can you tell us which method in the CashRegister class is represented as ringing up an item? If you found it, what you need to do is to add a variable type integer which will be increased by 1 each time an item is counted as purchased to the class. Remember to declare it as the class's variable, not a method's variable.
