Your task is to create a BankAccount class.
Class name
BankAccount
Attributes
_balance
float
_pin
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withraw (amount) should check if the amount can be withdrawn (not more than is in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 () should return the current balance.…

The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.arrow_forward14.23 LAB: Dean's list Students make the Dean's list if their GPA is 3.5 or higher. Complete the Course class by implementing the get_deans_list() instance method, which returns a list of students with a GPA of 3.5 or higher. The file main.py contains: . The main function for testing the program. Class Course represents a course, which contains a list of student objects as a course roster.

- Python Programming- Invoice Class Introduction: Requires creating classes and instantiating objects from created class Instructions: Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as data attributes--a part number (a string), a part description (a string), a quantity of the item being purchased (an int.) and a price per item (a Decimal). Your class shold have an __init__ method that intializes the four data ttributes. Provide a property for each data attribute. The quantity and price per item should each be non-negative--use validation in the properties for these data attributes to ensure that they remain valid. Provide a calculate_invoice method that returns the invoice amount (that is, multiplies the quantity by the price per item). Demonstrate class Invoice's capabilities. Once you have written the class, write a program that creates two Invoice Objects to hold…arrow_forwardCourse Title: Modern Programming Language Please Java Language Code Question : Create a class called with your 18Arid2891, as Invoice18Arid2891, that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0.

The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.arrow_forward
