Prerequisites

• Java Development Kit (JDK) 11 or higher
• Maven (optional, for building with Maven)

Compiling and Running the Application

Creating a Standalone Executable (recommended)

1. Open a terminal/command prompt
2. Navigate to the project root directory
3. Run: mvn clean package
4. Find the executable JAR file in the target directory: target/BankingApp.jar
5. Run the application by double-clicking the JAR file or using the command:

   java -jar target/BankingApp.jar
   

Using an IDE

1. Open the project in your IDE (Eclipse, IntelliJ IDEA, VS Code, etc.)
2. Build the project using the IDE's build functionality
3. Run the BankingApp class

Using Maven

1. Open a terminal/command prompt
2. Navigate to the project root directory
3. Run: mvn clean compile
4. Run: mvn exec:java -Dexec.mainClass="com.example.helloworld.BankingApp"

Using Java Compiler Directly

1. Open a terminal/command prompt
2. Navigate to the project root directory
3. Compile the code:

   mkdir -p target/classes
   javac -d target/classes src/main/java/com/example/helloworld/*.java src/main/java/com/example/helloworld/*/*.java
   

4. Run the application:

   java -cp target/classes com.example.helloworld.BankingApp
   

Data Files

The application uses CSV files to store data:

• account_balances.csv: Contains account numbers, holder names, and current balances
• transactions.csv: Records all transactions with timestamps

You can view and edit these files directly using a text editor or spreadsheet application.

3. List all accounts
4. Exit

After selecting an account, you can:

1. Make a deposit
2. Make a withdrawal
3. Perform multiple transactions
4. View transaction history
5. Update account holder name
