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

    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.

    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?
