In the constructor of DatabaseException class, what is the purpose of using String.format()?

To throw a formatted exception
To format the exception message
To convert exception to string
To calculate exception severity

The correct answer is: To format the exception message

String.format() is a useful method that allows for the formatting of strings based on specified parameters. In the context of the DatabaseException class constructor, we want to use this method to format the exception message so that it is clear, concise, and informative to the user. This is important because it helps to provide context about the error and how it occurred, which helps with debugging and troubleshooting. Option A is incorrect because it does not accurately describe the purpose of String.format() in this scenario. Option C is incorrect because it refers to converting the entire exception instead of just the message. Option D is incorrect because calculating exception severity would involve a different method or logic.
