Just clarifying: The purpose of the method is to add up EACH new apple_object price, and not to display the price of the last apple_object.
It wasn't difficult for me to reference the Class's variable, and to assign it the variable passed as argument. My difficulty was to understand what it was asked of me to do with it from the description statement. I mistakenly thought it was to print the last known price, not to accumulate all the p

1,000 Exceptions, but Code Displays Fine
I felt like I had all of the steps worked out and the code made sense to me. But when I ran and verified... it blew up in my face. A lot of exceptions and red font on the console, not a single green check, and not even a coherent-looking grid. Any hints to help me advance on this one?

Can you move the copyData line outside of the while loop?
I already completed the task, but after that I was looking at the code and I thought it seems really inefficient to be writing the entire ZipInputStream to a dummy copy on every iteration of the while loop. If it's a large archive this could really bog down the process. I was wondering if it would w

Why is the while argument !isExit on the correct solution?
I can understand the rest of the solution, but I don't understand why the argument for 'while' is !isExit. if boolean isExit = false, then surely !isExit = true and therefore the while loops stops straight away? Can someone clarify for me please?
