Question: 1 / 510

Which of the following is usually NOT a valid reason to use the finally block?

To release resources such as file handles

To perform cleanup such as closing database connections

To roll back a transaction if an exception occurs

To exit the program

The finally block is generally used to perform cleanup operations after the corresponding try and catch blocks have executed. Option D, "To exit the program," is usually not a valid reason for using the finally block as it does not align with the purpose of the finally block. The other options (A, B, and C) are all valid reasons for using the finally block as they involve cleanup and/or resources management. For example, releasing resources such as file handles and closing database connections are important to prevent memory leaks and improve performance. Rolling back a transaction if an exception occurs is also important for maintaining data integrity.
