This is a simple Java-based Banking Application that allows users to create accounts, deposit money, withdraw money, view account details, and update their contact information. The application simulates a basic banking system with support for multiple accounts, including necessary validation for account creation, deposits, withdrawals, and updates.

• Create a New Account: Allows the user to create a new account by providing a name, email, phone number, and an initial deposit.
• Deposit Money: Enables users to deposit a specified amount into their account. It includes validation for positive amounts.
• Withdraw Money: Allows users to withdraw money from their account, ensuring they don't withdraw more than the available balance.
• View Account Details: Displays the account number, account holder's name, balance, email, and phone number for a specified account.
• Update Contact Details: Provides the ability to update an account's email and phone number.
• Error Handling: Includes error handling for invalid input such as incorrect account number formats, negative amounts, and invalid email or phone number formats.

• Java Development Kit (JDK) version 8 or higher.
• A text editor or an IDE (e.g., IntelliJ IDEA, Eclipse, etc.) to run the application.

Make sure you have the Java Development Kit (JDK) installed on your system. Open a terminal or command prompt and navigate to the directory containing the BankingApplication.java file.
