Advanced Java Programming with Object-Oriented Programming Design

VERY IMPORTANT NOTE!!: This program for the question below MUST USE at least 2 CLASSES, getters/setters, etc and other object-oriented design (OOD) concepts because I'm in a more advanced Java class that requires me to utilize the concepts mentioned above. Also, I need detailed, but brief comments to most, if not all of the code to explain what is being used in the code and what is does so I have a better understanding of the code. I've seen answers to the question below already posted, however they don't utilize object-oriented design (OOD) concepts such as a minumum of two classes, getters/setters, etc which is required for this advanced Java programming class. So please......answer the question and meet the requirements for this question. Basically, I need advanced Java object-oriented design concepts for simple programs so here's to hoping this works out and if it does, I'll give a thumbs up, I promise!!!

One problem in CAI environments is student fatigue. This can be reduced by varying the computer's responses to hold the student's attention. Modify the program of Exercise 6.35 so that various comments are displayed for each answer as follows: Possible responses to a correct answer: Very good! Excellent! Nice work! Keep up the good work! Possible responses to an incorrect answer: No. Please Wrong. Try once more. Don't give up! No. Keep trying. Use random-number generation to choose a number from 1 to 4 that will be used to select one of the four appropriate responses to each correct or incorrect answer. Use a switch statement to issue the responses.
