      for(String string : strDesc)
      {
         System.out.println(string);
      }
      // arrays.sort
      Arrays.sort(strDesc, Collections.reverseOrder());   
      System.out.println("-----------------------------------");
      System.out.println("Sorting string array in descending or reverse order: ");
      for(String string : strDesc)

      al.add("Fox"); 
      al.add("Deer"); 
      al.add("Cheetah"); 
      al.add("Anteater");
      al.add("Elephant");
      System.out.println("Before sorting ArrayList: " + al);
      Collections.sort(al); 
      System.out.println("After sorting ArrayList in Ascending order: " + al);
   }
}
