Java simulation Bank Self-Service terminal system _java

A This system simulates the bank user to use the ATM machine to open accounts, inquires, the deposit, the withdrawal function, requests uses the Java language programming realization.

Description

1. For data entry exceptions, you can use the Java exception handling mechanism for processing.

2. The grading will be evaluated in a way that combines functional implementation with code standardization.

3. If you have questions about the project needs, you can contact me at any time by QQ message to consult.

4. National Day holiday period, every day teachers in the company on duty, October 4 is my company on duty, October 7 normal work, welcome everyone to the company to do the project.

Two Project Functional Requirements:

Three Design Requirements

(i) package one: Com.bank.unionpay for UnionPay, added under the package:

Represents the interface of a bank card that contains an abstract method of checking balances, deposits, withdrawals, and so on.
Represents an abstract class of ATM machines, using the bank card type Object as a property or parameter, to realize the query balance, deposit, withdrawal and other instance methods, add account for abstract method.
Enumeration type representing four major banks: including Abc,icbc,ccb,boc; on behalf of ABC, ICBC, CCB, BOC.

(ii) package two: Com.bank.abc said ABC, under the package added:

Defines a bank class in single mode, containing attributes: Bank type (enum type, constant =ABC), bank name (String), bank card list (collection), and so on.
Define the implementation class for the bank card-card, including attributes: Bank type (enumeration type =ABC), name, ID number, card number, password, balance, realization of the balance of inquiries, deposits, withdrawals and other methods.

Define the subclasses of ATM, including attributes: Bank type (enumeration type, constant =ABC), to implement the method of opening an account, in which: only card, card number 6-digit random number, automatically generated. The newly opened bank card is added to the bank card list.

Define subclass of card-credit card, add attribute: Overdraft limit, rewrite withdrawal method, control maximum withdrawal amount cannot be greater than balance + overdraft limit.

(iii) package Three: Com.bank.test represents the test, under the package to add a test class with the main method to achieve the project requirements of the simulation ATM function.

The following features are selected:

In the form of a single state of ICBC, in the test class by default to add more than a bank card, on ABC's ATM machine to achieve cross query and deposit and withdrawal function.
