  public static void main(String[] args) {
   ArrayList<String> c1= new ArrayList<String>();
          c1.add("Red");
          c1.add("Green");
          c1.add("Black");
          c1.add("White");
          c1.add("Pink");

          ArrayList<String> c2= new ArrayList<String>();
          c2.add("Red");
          c2.add("Green");
          c2.add("Black");
          c2.add("Pink");

          //Storing the comparison output in ArrayList<String>
          ArrayList<String> c3 = new ArrayList<String>();
          for (String e : c1)
             c3.add(c2.contains(e) ? "Yes" : "No");
          System.out.println(c3);
