Java Multithreading, Level 2, Lesson 9

It tries starting with all words in the list and returns the longest result. It's worked with everything I've thrown at it, even the ones you guys have suggested. I think th

Java Multithreading, Level 7, Lesson 15

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?

For your information The solution using the contains() method does not pass the verification of points 3 and 4. The contains() method probably uses break and continue statements.
