- Object initializers let you assign values to any accessible properties of an object at creation time without having to invoke a constructor Question 19 options: a) True b) FalseTrue or False ___(1) An abstract class can have fields. ___(2) You can create an object from an abstract class _ _(3) An abstract class can have both abstract methods and methods that have method bodyINVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…
- Python Code please Point of Sale Write a program that will manage the point of sale in a store. Build the ItemToPurchase class with the following: Attributes item_name (string) item_price (int) item_quantity (int) Default constructor Initializes item's name = "none", item's price = 0, item's quantity = 0 Method print_item_cost() Example of print_item_cost() output:Bottled Water 10 @ $1 = $10 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. Example of print_item_description() output:Bottled Water: Deer Park, 12 oz. 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…True or false: Just as a class can have multiple constructors, it can also have multiple destructors.subject :- object oriented programming python assume a typical luggage contains shirts, jackets, pants, and socks, among other items. It may also include DVDs with operating systems such as Windows 11, Ubuntu Linux, and MacOS. It can also store games and movie DVDs in addition to software DVDs. It could also include some basic hardware tools like a hammer, screwdrivers, and scissors. You'll design classes for the luggage object and the objects it holds using an object-oriented approach. Except for abstract classes, each class should include at least one attribute and one feature method (a unique function that belongs to that class, such as cut() in the Scissor class). Keep in mind that for objects with similar features and behaviors, you should attempt to design abstract classes. Define suitable class relationships like aggregation, composition, and association as well. Create a UML class diagram to represent your classes and their relationships.
- Sequence diagram Create a UML sequence diagram that will show your clients how the system’s classes will interact when customers are buying their flight tickets on the booking website. How to create your assignment Review the code responsible for adding a new item. Make a sequence diagram that captures the interactions of objects in the app when a new item is added. Your sequence diagram should contain the following classes: AddItemActivity ItemList Dimensions Item And contain calls of the following methods: onCreate() loadItems() saveItem() Dimensions constructor Item constructor addItem() saveItems() Lastly, the activation of AddItemActivity should start with the call to “onCreate()”Focus on classes, objects, methods and good programming styleYour task is to create a BankAccount class. Class name BankAccount Attributes __balance float float __pin integer integer Methods __init_()get_pin()check_pin()deposit()withdraw()get_balance() The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0.get_pin()should return the pin.check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not.deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance.withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not.get_balance()…
