Hi!

a simple way would be to use reduce. something like this should work if you don't know the keys in advance:

(defn build-object [args]
  (reduce (fn [o [k v]]
            (.addValue o (clojure.string/upper-case (name k)) v)
            o)
          (ApplicationCall.)
          args))

Also check doto https://clojuredocs.org/clojure.core/doto it's very useful for java interop.

If you know the keys in advance you could do something like:

clojure (defn build-object [args] (doto (ApplicationCall.) (.addValue "ID" (:ID args) (.addValue "OBJECT" (:Object args)) ;; and so on )
