Dear!
Loading the file:
(ns fly.bird)
(defprotocol Fly
(fly [this])
(fly [this x]))
(defrecord Bird [nom species]
Fly
(fly [this] (str (:nom this) " flies.."))
(fly [this x] (str (:nom this) " flies " x)))
got this error message:
java.lang.IllegalArgumentException: Can't define method not in
interfaces: fly (bird.clj:7)
What's wrong with this file. Thanks in advance.
Sincerely,
Ru
