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 ?
Thanks,
MH
