Question

1A). Write an application that creates a quiz, which contains at least 5 questions about a hobby, popular music, astronomy, or any other personal interest. Each question should be a multiple choice question with at least 4 options. When the user answers the question correctly, display a congratulatory message. If the user responds to a question incorrectly, display an appropriate message as well as the correct answer. At the end of the quiz, display the number of correct and incorrect answers, and the percentage of correct answers. Save your file as Quiz.java.

1B). Modify the application above so that the user is presented with each question continually until it is answered correctly. Remove the calculation for percentage of correct answers--all users will have 100% correct by the time they complete the application. Save your file as Quiz2.java.
