Re: a simple question about Arrays.asList
Hi Aaron, Thank you for your reply. I was able to understand. > Why are you trying to use Arrays#asList btw? There are probably better ways to do what you're trying to do. I just wanted to test reify to implement java.util.Comarator as follows: (java.util.Collections/sort x (reify java.util.Comparator (compare [this x y] (Integer/compare x y Initially, I gave a test data like this. (def x (doto (java.util.ArrayList.) (.add 3)(.add 1)(.add 2))) However, I thought asList is better. Are there better ways to do ?

Re: convert between PersistentArrayMap and HashMap
You are right. As you pointed out, my java interface design is not good. I've changed java interface into java.util.Map and I could pass Clojure's map to the java interface. I've also tested clojure.walk/postwork. The clojure.walk library is fine ! Thanks, Makoto -- You received this message because you are subscribed to the Google Groups "Clojure" group.
