public class ReadingSystemInstalled {


    public static void main(String a[]) {
        Map m = System.getenv();
        Set ref = m.keySet();
        Iterator it = ref.iterator();
        System.out.println("---------------");
        while (it.hasNext()) {
              //  System.out.println((String) it.next());
                String key=(String) it.next();
                System.out.println(key+" : "+m.get(key));


        }
       
    }
}
