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!!!

The use of computers in education is referred to as computer- assisted instruction ( CAI). Write a program that will help an elementary school student learn multiplication. Use the rand function to produce two positive one- digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the students answer. If its correct, display the message " Very good!" and ask another multiplication question. If the answer is wrong, display the message " No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.
