Clojure, printing inside a loop

Question

I made a simple function in Clojure to print some values.

(defn printboard [] (
    (dotimes [n 3]
      (println n)
      )
    )
  )

(printboard)

Now when i run this code as an application, it gives me an NullPointerException. When i run the code in the REPL it works perfect. Why does my code give me an NullPointerExeption in the application but not in the REPL?

You are wrapping dotimes inside parentheses. Try the below code

(defn printboard []
    (dotimes [n 3]
      (println n)))

(printboard)

Try it online!
