Java vs Clojure verbosity


Just comparing some cases of verbosity.

Is String blank?

Java
public class StringUtils {
    public static boolean isBlank(String str) {
        int strLen;
        if (str == null || (strLen = str.length()) == 0) {
            return true;
        }
        for (int i = 0; i < strLen; i++) {
            if ((Character.isWhitespace(str.charAt(i)) == false)) {
                return false;
            }
        }
        return true;
    }
}
Clojure
(defn blank? [s] (every? #(Character/isWhitespace %) s))
