          LinkedList<String> c1= new LinkedList<String>();
          c1.add("Red");
          c1.add("Green");
          c1.add("Black");
          c1.add("White");
          c1.add("Pink");
          System.out.println("Original linked list: " + c1);
          // Replacing 2nd element with new value
          c1.set(1, "Orange");
          System.out.println("The value of second element changed.");
          System.out.println("New linked list: " + c1);
