Create a class called Account that has the following attributes:
Account
Client - AccountHolder
Double - Balance
Date - DateCreated
Account()
Account(Client AccountHolder, Double Balance)
getAccountHolder() - Client
setAccountHolder(Client) - void
getBalance() - Double
deposit(Double) - Double
withdrawal(Double) - Double
getDateCreated() - Date
toString() - String
compareTo(Account) - Integer
equals(Account) - Double
Notes:
The account holder attribute will link to the Account class that you created in problem 6.
Your constructor and overloaded constructor should set the date created to the current date.
Your deposit method should add to the balance
Your withdrawal method should remove from the balance, as long as there is enough money to withdrawal
Write a class named SavingsAccount, which allows an owner of an account to make deposits and withdrawals. These accounts also compute interest periodically (use an interest rate of 0.02). The account should allow the user to enter his/her name, PIN, and balance as attributes when an account is created, and it should return an account number for the user to use. The class should include the following functions: (createAccount, verifyInfo, getBalance, getName, getPin, deposit, withdraw, computeInterest).
When an account is created, the balance should be zero by default. When the account user wants to access the account for withdrawal, deposit or computInterest, the program should check the user’s information against the information in the account created.
Use import statements to create the object and call each function.
Write a unittest program that tests the program above PYTHON

An Invoice should include four pieces of information as instance variable Part number(type String) Part description(type String) Quantity of the item being purchased (type int) 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. Write a test application named InvoiceTest that demonstrates class Invoice’s capabilities.arrow_forward
- (Java) Create a class named Customer that will determine the monthly repayment amount due by acustomer for a product bought on credit. The class has five fields: customer name, contactnumber, product price, number of months and the monthly repayment amount. Write get and setmethods for each field, except for the monthly repayment amount field. The set methods mustprompt the user to enter the values for the following fields: customer name, contact number,product price and number of months. This class also needs a method to calculate the monthlyrepayment amount (product price divided by the number of months).Add a subclass named Finance_Period that will determine if a customer will pay interest or not. Ifthe number of months to pay for the product is greater than three, the customer will pay 25%interest, or else no interest applies. The maximum number of months to pay for the product is 12.Override the calculate_repayment() method by determining if the customer will pay interest ornot…arrow_forwardPart A Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent.
