for each loop Properties

  • For each loop is the best choice to retrieve elements of arrays and collections.
  • for each loop is only applicable to arrays and collections.
  • By using normal for loop we can print array elements either in the original order or in reverse order, but by using for each loop we can print array elements only in the original order.

        for(String month:months){
            System.out.print(month + " ");
