Printing the class-path in Clojure

Let’s compare how we print the class-path in Clojure and how we do it on Java.

In Clojure:

(println (seq (.getURLs (java.lang.ClassLoader/getSystemClassLoader))))

In Java:

import java.net.URL;
import java.net.URLClassLoader;

public class PrintClasspath {
    public static void main(String[] args) {
        //Get the System Classloader
        ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader();

        //Get the URLs
        URL[] urls = ((URLClassLoader)sysClassLoader).getURLs();

        for(int i=0; i< urls.length; i++)
        {
            System.out.println(urls[i].getFile());
        }
    }
}

To be fair, the output is not the same, but the effect is.
