Bank Management System

A comprehensive Java-based Bank Management System designed for learning core banking operations and file handling concepts. This beginner-friendly project demonstrates object-oriented programming principles and command-line interface development.

Overview

This project simulates a basic banking environment that enables users to create and manage bank accounts through an intuitive command-line interface. The system is ideal for students and developers learning Java programming, object-oriented design patterns, file I/O operations, and user interaction implementation.

Features

• Account Creation: Set up new bank accounts with essential customer information
• Account Management: View detailed information for individual accounts
• Financial Operations:
  • Deposit Funds: Add money to any active account
  • Withdraw Funds: Remove money with built-in balance validation to prevent overdrafts
  • Balance Inquiry: Instantly check current account balances
• Account Modifications: Update customer details for existing accounts
• Account Deletion: Remove bank accounts from the system
• Data Persistence: All account information is stored in text files for persistence across application restarts

Directory Descriptions

• src/: Contains Java source files implementing account logic and application flow
• data/: Directory for persistent account data files
• build/: Compiled class files and build artifacts

Getting Started

Prerequisites

• Java Development Kit (JDK) 8 or higher
• Java IDE (Eclipse, IntelliJ IDEA, VS Code) or command-line tools
• Basic understanding of Java programming

Installation

1. Clone the Repository

   git clone https://github.com/code-divyu/Bank-Management-System.git
   cd Bank-Management-System

2. Set Up Your Development Environment

   • Import the project into your preferred Java IDE
   • Ensure all source files are in the classpath
   • Verify the data/ directory exists for file storage

3. Compile and Run

   # Compile all Java files
   javac -d build/classes src/*.java
   
   # Run the application
   java -cp build/classes Main

Usage

When you launch the application, you'll see a menu-driven interface with the following options:

1. Create Account - Register a new customer account
2. View Account Details - Display account information
3. Deposit Money - Add funds to an account
4. Withdraw Money - Remove funds (with balance validation)
5. Check Balance - View current account balance
6. Edit Account - Modify customer information
7. Delete Account - Remove an account from the system
8. Exit - Save changes and close the application

Note: All data is automatically persisted to accounts.txt in the data/ directory.

Technologies & Concepts

Core Technologies

• Java: Object-oriented programming, Collections Framework
• File I/O: Text-based data persistence
• Console Application: Command-line user interface

Programming Concepts Demonstrated

• Object-Oriented Programming (OOP)
• Exception Handling
• File Operations and Data Persistence
• Input Validation
• Menu-Driven Programming
• Basic Banking Logic Implementation

Example Workflow

1. Launch the Application

   java -cp build/classes Main
   

2. Create a New Account

   • Select option 1 from the main menu
   • Enter customer details (name, initial deposit, etc.)

3. Perform Banking Operations

   • Deposit funds using option 3
   • Withdraw money using option 4
   • Check balance with option 5

4. View and Manage Accounts

   • Review account details with option 2
   • Edit customer information with option 6
   • Delete accounts if needed with option 7

5. Data Persistence

   • All changes are automatically saved to data/accounts.txt
   • Data persists across application sessions
