Quiz class
Instructions
Given the attached Question class and quiz text, write a driver program to input the questions from the text file, print each quiz question, input the character for the answer, and, after all questions, report the results. Write a Quiz class for the driver, with a main method. There should be a Scanner field for the input file, a field for the array of Questions (initialized to 100 possible questions), and an int field for the actual number of questions. The constructor should instantiate the Question array, open the file with the Scanner, and input the Question array from the input file. Note that one of the constructors for the Question class takes a Scanner parameter and initializes an entire question from the Scanner. There is a blank line at the end of the file, so hasNextLine() would work for the loop. After the input loop, the count field should be the number of questions. A give() method should declare and instantiate a Scanner for keyboard input, counters for correct and incorrect answers, an array (or ArrayList) of ints for the numbers that were incorrect, and an array (or ArrayList) of chars for the answers that were incorrect. It should loop through each question and print it out, prompt for the answer, count it if it is right and save the question number and wrong answer in the two arrays (or ArrayLists) if it is wrong. After this loop, it should print out the number correct and the numbers that were wrong, with the wrong answers. The main method should just instantiate a Quiz and call its give() method.
