Why don't we have a unique Collection data type that uses methods to add items, remove the most recently inserted item, remove the least recently inserted item, remove random, iterate, return the total number of items in the collection, and whatever other actions we may need? Then we could build each one in a singular class that many clients could use.

- Q. Why not have a single Collection data type that uses methods for adding items, removing the most recently inserted items, removing the least recently inserted items, removing random items, iterating, returning the number of items in the collection, and performing any other actions we may require? Then we could combine them all into a single class that could be used by many customers.Why not create a single Collection data type that includes methods to add items, remove most recently inserted items, remove least recently inserted items, remove random items, iterate, return the collection's item count, and any other actions we might need? Then we could build each one in a single class that many clients could use. ans in 10 minThis is the question that is confusing me - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course…
- Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.implement a database about people, they could be made up, but you want to include a sizable number, maybe 10-20. The data that you store for each person must include a name and at least one additional piece of information, such as a birthday. You can assume that the names are unique. The database should enable you to enter, remove, modify, or search this data. You also should be able to save the data in a file for use later. Define a class Person to represent a person and another one to represent the database. A dictionary should be a data member of the database class, with Person objects as search keys for this dictionary. Write a program that tests and demonstrates your database.Extend the functionality of the Carinventory class by introducing a new method called 'add_car. This method should facilitate the addition of custom cars to the inventory. The method should take two parameters: a car model and its price. Implement this method to ensure that the inventory is updated accordingly. Instantiate a new object of the car inventory, naming it 'Auto Emporium,' utilizing the extended class with the newly added 'add_car' method. Your next step is to add three distinct custom cars to 'AutoEmporium'-for example, "Sleek Sedan,' 'Sporty Convertible,' and 'Luxury SUV: Assign varying prices to each of these cars. To conclude, utilize the 'display_inventory method to showcase the updated information about 'AutoEmporium." Verify that the output includes details about the newly added custom cars, ensuring that the prices are accurately reflected. This question tests the candidate's ability to implement a specific method, instantiate objects, add custom items, and…
- Part 2: Sorting the WorkOrders via dates Another error that will still be showing is that there is not Comparable/compareTo() method setup on the WorkOrder class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the WorkOrder class. The compareTo() method will take a little work here. We are going to compare via the date of the work order. The dates of the WorkOrder are saved in a MM-DD-YYYY format. There is a dash '-' in between each part of the date. You will need to split both the current object's date and the date sent through the compareTo() parameters. You will have three things to compare against. You first need to check the year. If the years are the same value then you need to go another step to check the months, otherwise you compare them with less than or greater than and return the corresponding value. If you have to check the months it would be the same for years. If the months are the same you…Extend the ItemToPurchase class to contain a new attribute. item_description (string) - Set to "none" in default constructor Implement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object. Has an ItemToPurchase parameter. Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps. Parameterized constructor which takes the customer name and date as parameters Attributes customer_name (string) - Initialized in default constructor to "none" current_date (string) - Initialized in default constructor to "January 1, 2016" cart_items (list) Methods add_item() Adds an item to cart_items list. Has parameter ItemToPurchase. Does not return anything. remove_item() Removes item from cart_items list. Has a string (an item's name) parameter. Does not return anything. If item name cannot…For this task you will need to implement a Guesses class, which will store all of the locations that a player has targeted/guessed so far. Again, the included Runner class is provided purely so you can manually debug your code by hitting the Run button and observing the results. It is not included in any tests, so feel free to make any changes you like to it. Your workspace for this task includes a compiled Cell class, that has been implemented according to the specification described in Part 1. Specification We have started you off with the skeleton of the Guesses class. Your task is to complete this class so that it has the following methods: A constructor that accepts no parameters, and results in a new instance of Guesses being created. An addGuess method, which accepts an instance of Cell, and returns nothing. Calling this method should result in this instance of Guesses remembering that the given location has been guessed. An isGuessed method, which accepts an instance of Cell,…
- company wants to make a simple application to keep track of trips andpassengers.you got the following information:3 classes needed one super class Trip and sub classes Passenger and Driver.• It is required to store the whole data in one collection The Trip class has:1- a number2-a driver3-a specific date.4- In addition, passengers could be added or removed within a given limit for the maximum number of passengers who could be in thesame trip.5- there are other attributes (add at least 3 attributes from your choice).6- trip number is unique within the same date. The Driver class has:1- a unique ID2- a name3- other attributes (add at least 2 attributes from your choice). the Passenger class has:1- a unique Civil ID (National ID)2- a name3- other attributes (add at least 2 attributes from your choice but one of them should be common with drivers).
