Building the Project

To build all modules:

mvn clean install

To build a specific module:

cd bank
mvn clean install

To compile without running tests:

mvn clean compile

Module Details

bank

The bank module contains a sample bank application with various errors and bad practice examples which can be detected by Jtest analysis.

Key Components:

• Bank.java - Main bank class managing accounts
• Account.java - Bank account representation
• Customer.java - Customer information
• CreditCard.java - Credit card management
• Transaction classes for deposits and withdrawals
• Error handling and logging utilities

atm

The atm module contains the ATM (Automated Teller Machine) banking terminal application. An ATM allows customers to perform financial transactions such as withdrawals, deposits, and balance inquiries without needing a human teller.

Origin: Converted from C++ to Java implementation with enhanced interactive features.

Key Components:

• ATM.java - Main ATM controller with interactive menu system and transaction processing
• Account.java - ATM account representation with balance management
• Bank.java - Account management system for ATM operations
• BaseDisplay.java - User interface for displaying messages and balance information

Interactive Features:

• Main Menu:

  • Create new accounts with password protection
  • Login to existing accounts
  • Exit application

• Transaction Menu (after login):

  • View current account balance
  • Deposit money into account
  • Withdraw money from account
  • Logout and return to main menu

Running the ATM Application:

# Compile the project first
mvn clean compile

# Run the ATM application
java -cp atm/target/classes com.parasoft.jdemo.atm.ATM

Usage Example:

1. Create a new account with initial deposit and password
2. Login using your account number and password
3. Perform transactions (view balance, deposit, or withdraw)
4. Logout when finished

Dependencies:

• Depends on the bank module for banking operations

Technology Stack

• Java: 11
• Build Tool: Maven
• Testing: JUnit 5 (Jupiter), JUnit Vintage, Mockito
• Quality Analysis: Parasoft Jtest

Maven Reactor

The project uses Maven's multi-module reactor build. The build order is:

1. Parent POM
2. bank module
3. atm module (depends on bank)

Development

The project is configured with:

• UTF-8 source encoding
• Java 11 source and target compatibility
• Shared dependency management in parent POM
• Common plugin configuration for all modules
