Java Syntax, Level 7, Lesson 9
Resolved
Null pointer exception?? What is wrong? I have tried printing out whole array in "print 1" and "print 2" first one prints out the list and the second one does not print nothing just "null" so somehow my "list = fix(list)" makes the arraylist null? any ideas why?

Super lost help I understand that between ADDED and REMOVED you have to have a SAME line between them. What I don't understand is how exactly the content of the files are layered. One attempt I tried timed out and I thought it would work but time is a factor of course.

Question about the task CRUD
Java Core, Level 7, Lesson 10
Resolved
Don't get why my code doesn't pass 3rd+4th conditions The output seems correct if I use "-i 1" in the Program arguments. If I add a new person with "-c" etc etc, I get "2" as output, which is its index and what is supposed to happen, as far as I understood from the conditions. Don't new people get added to the end of the list automatically?
