Using interop constructor in map function(Clojure)

Question

I am getting this complaint when passing Integer constructor to map function :

=> (map Integer. [\"1\" \"2\" \"3\"])
CompilerException java.lang.ClassNotF         


        

Answer 1

map takes in a function and interop uses a special forms like new . and .. It is fairly easy to wrap these with anonymous function literals

for example

(map #(Integer. %) ["1" "2" "3"])

produces the desired result.
