Unfortunately, Rich Hickey (the inventor of Clojure) didn't think that importing all the classes from a package into the program's namespace was a good idea 1 , so that's what he implemented. As a result, you must explicitly name each Java class that you want to use.
Listing 3 shows the ns (short for namespace ) form that begins my Clojure program (Listing 2 occurs later in [url=http://www.fal.es/fal.php]Oakley Baratas[/url] the same Clojure source file). There is an import macro in Clojure that can also be used, but using the import: keyword within the ns form at the top of your program is the preferred [url=http://www.staimanmedia.com/ray-ban.php]Fake Ray Bans UK[/url] method of importing in the Clojure community.

Each form inside the (:import ) clause has the following syntax:
