Project Description

This Java project implements a simple banking system with abstract and concrete classes, as well as interfaces to represent different entities of the bank. The system allows for the creation of bank employees, clients with associated addresses, and the performance of basic banking operations such as deposits, withdrawals, and transfers.

Requirements

1. Creation of Abstract Classes:

   • The Account and Person classes are abstract classes, meaning objects cannot be instantiated from these classes.

2. Creation of the IUser Interface:

   • The IUser interface has only the signature of a method.
   • The method, when implemented in the classes that perform the interface, must return only True.

3. Creation of Concrete Classes:

   • The concrete classes correspond to all other classes, and some of them have inheritance relationships with the abstract classes of the model.

Considerations about Methods in Concrete Classes:

a. listAddresses() Method of the Client Class: - The method should print to the console all addresses stored for a client.

b. deposit() Method of the Account Class: - Creates an object of type Credit linked to the account receiving the deposit.

c. withdraw() Method of the Account Class: - Creates an object of type Debit linked to the account undergoing the withdrawal. - The account cannot have a negative balance beyond its limit.

d. transfer() Method of the CheckingAccount Class: - Withdraws money from the source checking account and sends it to a destination account. - The account cannot have a negative balance beyond its limit.

e. calculateBalance() Method of the SavingsAccount Class: - Sums the value of all credits and subtracts it by the sum of the values of all debits.

f. calculateBalance() Method of the CheckingAccount Class: - Sums the value of all credits and subtracts it by the sum of the values of all debits. - Then, adds the value of the limit. - Finally, returns the value.

Features

Feature 1:

• Create two bank employees, one manager and one teller.

Feature 2:

• Create a client and add 3 addresses to him/her.
• Print the addresses of this client.

Feature 3:

• Create a client who has a CheckingAccount.
• Make three deposits of 100 into this CheckingAccount.
• Make a withdrawal of 50 from this CheckingAccount.
• Print the balance of this CheckingAccount.

Feature 4:

• Create a client who has a CheckingAccount.
• Make a deposit of 1000 into this CheckingAccount.
• Create a client who has a SavingsAccount.
• Make a deposit of 1000 into this SavingsAccount.
• Transfer 500 from the CheckingAccount to the SavingsAccount.
