Banking System in Java

This project simulates a simple banking system. It allows users to create and manage bank accounts, perform deposits and withdrawals, and retrieve account details.

Overview of Components

BankAccount Class

• Purpose:

  • Represents a single bank account.
  • Provides methods to manage account data and operations.

• Key Attributes:

  • Account Number: A unique identifier for each bank account.
  • Customer Name: The name of the account holder.
  • Balance: The current amount of money in the account.

• Key Functions:

  • Constructor: Initializes a new account with an account number, customer name, and balance.

  • Getters: Methods to retrieve the account number, customer name, and balance.

  • Deposit Function:

    • Allows adding money to the account.
    • Validates that the deposit amount is positive.

  • Withdraw Function:

    • Allows removing money from the account.
    • Validates that there are sufficient funds and the amount is positive.

  • Display Function:

    • Prints the account details (account number, customer name, and balance) to the console.

Main Class

• Purpose:

  • Manages user interaction and operations related to multiple bank accounts.

• Key Functions:

  • User Input Handling:

    • Prompts users for the number of accounts and collects their details.

  • Menu Display:

    • Shows available options such as viewing account details, searching for accounts, depositing, and withdrawing funds.

  • Operations:

    • Display All Accounts: Lists all account details.
    • Search by Account Number: Allows users to find specific accounts.
    • Deposit and Withdraw: Facilitates the addition and removal of funds from accounts.

Project Workflow

1. Initial Setup:

   • The user specifies the number of customers/accounts to create.
   • The user enters details for each account.

2. Menu Navigation:

   • After creating accounts, a menu is presented for various operations:
     • View all accounts.
     • Search for a specific account.
     • Deposit or withdraw funds.

3. Account Management:

   • Users interact with their accounts through the menu options.
   • Operations are validated to ensure correctness (e.g., no negative amounts, sufficient funds).

4. Exit Process:

   • The application runs in a loop until the user decides to exit.

Conclusion

This project serves as a foundational example of a banking system in Java. It demonstrates essential programming concepts such as:

• Object-oriented design.
• User input handling.
• Basic data validation.

Future Enhancements

• Consider adding features like:
  • Different types of accounts (savings, checking).
  • Transaction history for accounts.
  • A graphical user interface (GUI) for better user experience.
