Question about downloading JDK I tried to download JDK from the oracle site but it asks me to log in. I don't have account so i tried to register new one. The problem is that it asks me to write info about my job title, job phone number adresses etc. Do i need it to end this course? Is it a way to get it without these informatio

Code works but not passing It is beginning to get annoying how often this happens. If they have further requirements, why not just list them? That is the point of test-driven development. Any thoughts as to what the other unlisted requirements are? Thanks!
