 the program will inform the user that their input is invalid, and provide the range of questions the user can attempt.
 
-If the input is not an integer, the program will inform the user that their input is of the wrong format, and probe them to enter a value of integer type.
-The method will then randomly select the input number of quiz questions in the quiz ArrayList and convert it into its string representation.
-This is then passed to the UserInterface#printArray() to be printed out to the user.
-When each quiz question is printed, the user needs to input an answer to this question.
-The input answer will then be compared to the answer of that quiz question.
-If the answers are the same, the variable correctCounter in QuizManager() will be incremented by 1. 
-Upon completion of this feature, it returns a boolean value “true” to the active flag in UserInterface.java to allow the continuous usage of the program.
