- Write the definitions of the member functions of the classes arrayListType and unorderedArrayListType that are not given in this chapter. The specific methods that need to be implemented are listed below. Implement the following methods in arrayListType.h: isEmpty isFull listSize maxListSize clearList Copy constructor Implement the following method in unorderedArrayListType.h insertAt Also, write a program (in main.cpp) to test your function.Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…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.
- Part #1: Write a method called equallists in a class called compare. The method accepts three ArrayList objects list1, list2 and list3 of type ArrayList as parameters. The list3 is to be generated by compare the list1 and list2 by the method, if both lists list1 items and list2 items are equal then write 1 in the same index in list3, else write 0. public class compare { public static boolean equallists mmmmmmmmm (ArrayList unnammmmm ArrayList list3) mmmmmmmmmmm Example: list1: 4 13 1 8 list2: 4 2 1 12 list3: 1 0 1 0 (generated by the method) listl, ArrayList Part #2: Write a class called Test equallists having main method to test the application. In main method create following: 1- Object of type ArrayList list1. 2- Add the following data to list1 (4 13 3- Object of type ArrayList list2. 4- Add the following data to list2 (4 5- Object of type ArrayList list3. 6- Test the equallists method to print the result. 1 9 0 9 0 1 2 05 0 10 2 list2, 18 1 901). 1 12 9 2 0 5).Computer Science Write a program in the Java language that includes: 1. A class for books, taking into account the encapsulation and getter, setter. 2. Entering books by the user using Scanner 3. LinkedList class for: (Adding a new book - Inserting a book- Searching for a book using the ISBN Number - Viewing all books,delete book). 4. Serial number increases automatically with each book that is entered. 5. Printing the names of books is as follows: Serial - ISBN - Name - PubYear - Price - Notes. 6-Design a main menu that includes: • Add Book • Insert Book • Delete Book • Search . Display . ExitIn java Write a class with a main() method. The main() method should declare and initialize four different ArrayLists, each containing at least four int values. The class should also contain a method named fiveEight. Given an ArrayList of ints, the fiveEight should return the int 30 if every element of the given ArrayList is either a 5 or a 8; otherwise, it should return -9. There should be four calls to the allfiveEight method in the main() method.
- Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)URGENtt!! You are asked to write a java class named "Kume". The UML class diagram of the Kume class is as follows. 3 The elements in the set are kept in an ArrayList. The constructor of the class takes an array of int and adds the elements of this array to the ArrayList named al. The add() method adds an integer it takes as a parameter to the get element. The delete() method deletes an Integer object that it takes as a parameter from the get element, returns true if it can be deleted, otherwise false. The print() function prints the elements of the set to the console. The compareTo() method is inherited from the Object class and is suppressed, and compares the get element of the Set object, which it takes as a parameter, with the retrieve element of the current set object in terms of content (the order of the elements is not important). It returns 1 if both sets contain the same elements, 0 otherwise. Below is a test code that creates two objects from the Kume class and performs…2. Write a class ArrayClass, where the main method asks the user to enter the four num bers. Create a method printArray that prints the array whenever required (use Acrav.toString method). Make the program run as shown in the Sample Run below. Green is user input. Use Attax.sort, Attach.bianrySearch. Attaveauals Sample Run List1, Enter four num bers: 2 33 2 List2, Enter four num bers: 6 25 4 List3, Enter four num bers: 52 46 Your original Listi: [2, 3, 3, 2] Your original List2: [6, 2, 5, 4] Your original List3: [5, 2, 4, 6] Sorted Listi is: [2, 2, 3, 3] Enter a number from the sorted List1 to search for: 3 Value 3 is in index 2 (or position 3) List that are the same when sorted: [2, 4, 5, 6]
- This program is going to maintain a list of customers’ names and bank account balances. 1. Create a class called CustomerList with a main method that instantiates an ArrayList of String objects called customerName. Invoke the add method to add the following names into the ArrayList: Cathy Ben Jorge Wanda Freddie 1. Print each name in the ArrayList using a for a loop. 2. Create another ArrayList object called customerBalance, to save users’ balance. What is the type of this ArrayList? double or Double? You just need to declare this ArrayList and leave it empty for now. 3. For each customer, print the name and ask the user to enter the initial balance for this customer. Save the initial balance into ArrayList customerBalance. Use a loop to get this done for all 5 customers. The program should print out this for the first customer: Example: Please enter the account balance for Cathy: (waiting for user’s input …) Code: for(int i=0; i<5;i++) { Print(“Please enter the account balance…Make a shopping cart program that implements the ArrayList class. Make a class named Item.java that contains the following data members, item_name, quantity, and price. Create the appropriate constructors and methods to initialize, access, and manipulate the data members, also create a toString method to print the item name, quantity, and price. Create an ArrayList of Items in the Main.For the INPUTThe user will enter the item name, quantity, and price of each item. A 'Y' will add another item to the shopping cart, and 'N' will stop the input.For the OUTPUTThe program then lists the items in the shopping cart using the toString method in the Item class. Calculate for the subtotal and total of the items in the cart.Format your toString method to have a double tab, "\t\t", after the item name, single tab, "\t", after quantity and double tab, "\t\t", after price.
