Part B: Exception Handling in Java

Objective: This assignment aims to strengthen your understanding of exception handling in Java by implementing error detection and handling mechanisms in a scenario involving user input validation and data processing.

Instructions:

$1.$ Description: In this task, you will develop a Java program that demonstrates your understanding of exception handling. You will create a program that simulates a simple banking system, where users can perform transactions such as deposits, withdrawals, and transfers. Your program should handle various types of exceptions gracefully to ensure smooth operation.

$2.$ Bank Account Class: Define a class named BankAccount with the following attributes and methods:

o Attributes: account number, account holder name, balance.

o Methods: deposit, withdraw, and display account information.

$3.$ Exception Handling: Implement exception handling in the BankAccount class to handle potential errors:

o Handle the scenario where the withdrawal amount exceeds the account balance by displaying an error message to the user.

o Handle the case of negative deposit or withdrawal amounts by displaying an error message to the user.

o Implement appropriate try$-$catch blocks in the deposit and withdraw methods to catch and handle these exceptions.

$4.$ Transaction Processing: Create a main program that simulates banking transactions:

o Create instances of BankAccount objects for multiple users.

o Allow users to perform transactions such as deposits, withdrawals, and transfers between accounts.

o Ensure that appropriate exception handling mechanisms are in place to handle any errors that may occur during transaction processing.

$5.$ Testing: Test your program with various scenarios, including valid and invalid transactions, to ensure that exception handling works as expected.

Evaluation Criteria: Your code will be evaluated based on the following criteria:

$$ Correct implementation of the BankAccount class with methods for handling transactions.

$$ Proper use of exception handling mechanisms to detect and handle errors.

$$ Clarity and completeness of error messages displayed to the user.

$$ Correctness of the banking transactions processed by the main program.

$$ Overall code organization, readability, and adherence to Java best practices
