Code the SinglyLinkedList class from our class notes (L03_). Override the toString method by using StringBuilder to list every element, in order from head to tail. In the same Lab3_Driver file, create a SinglyLinkedList instance called productList that holds a list of DairyProduct. Add elements into the SinglyLinkedList instance so that the following statement(in your driver file): System.out.println(productList); would display the following output: [Milk(4L) : 5.05, Cheese Sticks : 3.99, Yoghurt : 4.99, Ice cream(1L) : 2.99, Butter : 5.65, Drinkable yoghurt : 4.99] Note that your list must be built to contain and display these products in this order.
