How to get an Fn which calls a Java method?

Question

I\'m learning Clojure. I wrote this code to recursively walk a directory.

(tree-seq #(.isDirectory %1) #(.listFiles %1) (File. \"/my-directory\"))

You've already been given the correct answers, but just to add a bit more Clojure idiomatic code, I'd also use

#(.foo %)

as Joost Diepenmaat did (yet I believed it might've been overlooked).

I would also suggest reading Listing files in a directory in Clojure.
