I am working on a project that requires me to get the size of a file and access it's last date of modification. It seems like the java methods .length and .lastmodified could be pretty handy in this situation. I am, however, having a bit of trouble wrapping my head around how to access a jav

For reasons unclear to me, (into {} ...) expects a sequence of 2-element *vectors*, not just 2-element collections. partition returns a seq of lists, not vectors, which is why you're getting that exception. You could try (into {} (map vec (partition 2 2 "12"))) instead. On Mar 26, 2014, at 15:3
