Your Online Bank Account Has 2 Levels Of Security

Instructionsyour Online Bank Account Has 2 Levels Of Security Quest

Instructions : Your online bank account has 2 levels of security: question and password. You have 3 attempts to answer the question, and 2 attempts to enter the password. Use a do/while and a for loop to control the entries. One will be embedded in the other. One looping structure is better suited than the other as the outside loop.

Don’t forget to exit the main(). You don’t need to print the double quotes in the messages. Look at the sample output for prompt and spacing requirements. Print “Invalid answer! 9 more attempts.” where 9 represents the remaining attempts for an incorrect answer to the question. Print “Invalid password! 9 attempts left.” where 9 is the attempts remaining for a wrong password. Print “Trinity Bank & Trust - Account Management for Xxxxxxxxx” when all codes are entered correctly, with Xs representing your name. Use this Java code to test the password: if(password.equals("Bi!!y0562Fish")) Use this Java code to test the answer: if(question.equalsIgnoreCase("Chevy Camaro")) System.exit(0) only once at the end of main(). See attachment for sample output.

Paper For Above instruction

Developing a secure and user-friendly login system is essential for protecting sensitive financial information in online banking. This paper explores the implementation of a two-factor security process involving a security question and a password, managed through nested looping structures in Java. Utilizing do/while and for loops provides a controlled environment for limiting attempts and enhancing security.

The core logic involves giving users limited attempts to correctly answer their security question and subsequently enter their password. The system allows three attempts for the security question and two for the password. If either attempt fails, the system notifies the user of remaining attempts and prompts again, until attempts are exhausted. Correct entries result in successful access and display of a personalized message indicating account access.

Implementing such a system requires careful control flow to efficiently manage attempts and ensure proper termination once access is granted or attempts are depleted. A nested loop structure is suitable, with an outer do/while loop managing the question attempts and an inner for loop managing password attempts. Using only one of these as the outer loop, based on logic flow, enhances readability and efficiency. Since the outer loop handles the question, and the inner loop manages password attempts, this hierarchy ensures the process is sequential and controlled.

In the code, the system prompts the user for their answers, and after each incorrect attempt, displays the remaining attempts as specified. The string comparison utilizes equalsIgnoreCase for the security question, accommodating case-insensitive entries, while the correct password check relies on the equals method with the provided password string.

Once all correct entries are received, or all attempts are used, the program exits gracefully. Specifically, System.exit(0) is called at the end of main() to terminate the program. Proper handling of attempts and notifications ensures a user-friendly yet secure account access process, aligning with best practices for online banking security.
