Use java

Implement the Strategy pattern for quizzes/exams that have multiple types of questions.

• This assignment focuses on following the pattern, so dont worry about error-checking (like case sensitivity, whether there are any underscores in a FillIn question)
• You need to implement the following in the package school
  • Question: the Strategy interface for this assignment
    • Placed in the package school.assessment
    • This interface has a function mark(String ans) that returns true if its parameter is the correct answer, false if not
  • MultipleChoice: a concrete child class of Question
    • The constructor takes 3 parameters:
      • The String text to display to the user taking the quiz/exam
        • Ex: On which continent is the country of India?
      • A List for the possible answers to display
        • Ex: {Asia, Africa, Europe}
      • A String for the correct answer
        • Ex: Asia
    • The ans parameter for mark() is the answer chosen by a test taker, and mark() compares it to the correct answer set in the constructor
    • Override toString() to return a String with the text followed by each possible answer on a separate line
  • FillIn: a concrete child class of Question
    • The constructor takes 2 parameters:
      • The String text to display to the user taking the quiz/exam
        • Ex: University is in the city of _______
      • A String for the correct answer
        • Ex: Jersey City
    • The mark()returns true if the parameter equals the correct answer, false if not
    • Override toString() to return a String with the text to display
  • Quiz: a concrete class that contains a bunch of Question objects. It supports:
    • void add(Question question) to add a question to the quiz
    • int grade(List answers) to return the number of correct answers in the parameter
