Can't get the objects to print correctly My code as attached prints the hashCode for each object, 1 per line, but this doesn't meet the requirements. I'm trying to override the toString() method to correct this. But (after un-commenting lines 16-19), whatever I try to return causes an error. How do I fix this?
