hello world in clojure

This is an example of a "Hello, World!" program in Clojure:

(ns hello-world.core
  (:gen-class))

(defn -main
  "I print 'Hello, World!'"
  [& args]
  (println "Hello, World!"))

To run this program, you can use the Clojure REPL or save it to a file with a .clj extension, and then execute it using the clojure command followed by the name of the file.
