- Task 4. Utility classes Implement a Menu-Driven program of ArrayList class using the above scenario and perform the following operations. a. Create an object of ArrayList class based on the scenario with explanations of the method used. b. Create a method that will allow inserting an element to ArrayList Class based on the scenario. The input field must be validated as necessary. C. Create a method to delete specific elements in the ArrayList with explanations of the method used.arrow_forwardJava Program Requirements: Create a DodecahedronList class that stores the name of the list and an ArrayList of Dodecahedron objects. It also includes methods that return the name of the list, number of Dodecahedron objects in the DodecahedronList, total surface area, total volume, average surface area, average volume, and average surface to volume ratio for all Dodecahedron objects in the DodecahedronList. The toString method returns a String containing the name of the list followed by each Dodecahedron in the ArrayList, and a summaryInfo method returns summary information about the list. Design: The DodecahedronList class has two fields, a constructor, and methods as outlined below. (1) Fields (instance variables): a String representing the name of the list and an ArrayList of Dodecahedron objects. These are the only fields (instance variables) that this class should have. (2) Constructor: Your DodecahedronList class must contain a constructor that accepts a parameter of type String…arrow_forwardThis lab was designed to reinforce programming concepts from this lab, you will practice: Declaring and initializing ArrayList. Add elements to the Arraylist. Display the content of the ArrayList. Write a class name PhoneBookEntry that has fields for a person’s name and phone number. The class should have a constructor and the appropriate accessor and mutator methods. Then write a program that creates at least 5 PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.arrow_forward
