1. Implement the Course class.
   1. Add two private instance variables of type String to store the course code and course title of a particular course.
   2. Add a private instance variable of type double to store the number of credit hours for the course.
   3. Add a private instance variable that is an array of doubles that represents a collection of student scores.
   4. Communicate a four-argument constructor that takes the course code, course title, number of credit hours, and number of students in the course and does the following:
   5. Use the course code, course title, and number of credit hours to initialize the respective instance variables.
   6. Use the new keyword to initialize the array of scores to a new array whose length corresponds to the number of students in the class.
   7. Communicate a public void method called readScores that prompts the user to enter the score for each student in that course, and stores the score in the corresponding array element. Example input and output might look like this:
   8. Enter the course code: CSCI 4200 Enter the course title: Principles of Information Security Enter the credit hour: 3.0 Enter the number of students in the course: 6 Enters scores for 6 students 87 64 96 88 45 73
   9. Communicate a public void method called displayInfo that displays the course information in the following format:
   10. CSCI 4200: Principles of Information Security (3.0 credit hours) Class size: 6 Scores: 87 64 96 88 45 73
   11. Communicate code in the main class to test the Course class.
       1. Write a static method called createCourse that does the following:
          • Prompt the user for the course code, title, credit hour and class size.
          • Create an object of type Course using the 4-argument constructor and the values the user provided.
          • Return the Course object
   12. Add the following code to the main method:
       • Call the createCourse method to create a Course object and store it in a variable.
       • Call the readScores method to read scores of all students in the course.
       • Call the displayInfo method to display the results.
   13. Run your program to make sure that it works correctly.

1. Add additional methods to the Course class.
   1. Communicate a private helper method that calculates and returns the sum of all of the scores in the array.
   2. Communicate a public method called getAverage that computes the average score using the private helper method to calculate the sum and the length instance variable of the array.
   3. Communicate a public method called getMax that returns the maximum score in the course.
   4. Communicate a public method called getMin that returns the minimum score in the course.
2. Write code in the main method of the main class to test the new methods.
   1. Display the average score in the course using the getAverage method.
   2. Display the maximum score in the course using the getMax method.
   3. Display the minimum score in the course by calling the getMin method.
   4. Make sure to display exactly 2 digits after the decimal point when displaying each of the computed scores.
   5. If the input from step 4 is used, the output of the above tests should look like this:

• The average score is: 75.50 The maximum score is: 96.00 The minimum score is: 45.00
