Oh, I'm sorry, completely missed the getName part of the question! This will give you a list of names: (let [particles (-> dataLoader .getEnvironmentParticleSet .iterator iterator-seq)] (map #(.getName %) particles)) You can then do things to the names in a 'loop' with map, for, or doseq (if 'things' has side effects): ;; map (let [particles (-> dataLoader .getEnvironmentParticleSet .iterator iterator-seq) names (map #(.getName %) particles)] (map #(count %) names)) ;; for (let [particles (-> dataLoader .getEnvironmentParticleSet .iterator iterator-seq) names (map #(.getName %) particles)] (for [n names] (count n))) ;; doseq (let [particles (-> dataLoader .getEnvironmentParticleSet .iterator iterator-seq) names (map #(.getName %) particles)] (doseq [n names] (println n))) HTH! -- !
