Course Statistics

Class Course

The Course class represents an individual course object. It includes the following instance variables:

• String name: Stores the course name (e.g., CPSC215).
• String title: Stores the course title (e.g., Data Structures and Algorithms).
• int students: Stores the total number of students who have taken the course.
• int votes: Stores the total number of positive recommendation votes.

Constructors

• Default constructor and a parametrized constructor to set the instance variables.

Methods

• double getScore(): Calculates and returns the recommendation score, which is the percentage of students who recommend the course.
• String description(): Returns a String representation of a full course description.
• String toString(): Returns a String representation consisting of the course name and the recommendation score.

Class CourseStatistics

The CourseStatistics class maintains course statistics and uses the following data structures:

• A Map implemented with a hash table for storage.
• A PriorityQueue for recommending the best course to take. This queue uses a custom CourseComparator object to compare courses.
• It keeps track of the total number of courses added.

Methods

• void addCourse(Course c): Adds a course c if it's not yet stored or updates its totals if it is.
• Course getCourse(String name): Returns a stored course given its name.
• void findBest(List<Course> courses): Finds and displays the best course to take based on its recommendation score.
• void displayStats(): Displays all course names and their recommendation scores sorted by the scores.
• void displayAll(): Displays all courses and their descriptions provided by description().

Class CourseStatisticsTester

The CourseStatisticsTester class is a tester class for CourseStatistics. It produces the expected output as specified in Part 7 of your project requirements. A user can look up and compare any number of courses.

Class CourseComparator

The CourseComparator class implements the compare() method to compare objects based on their recommendation score as provided by getScore().

Usage

To use this project, you can create instances of Course, add them to a CourseStatistics object, and perform various operations to find and display course statistics. The CourseStatisticsTester class demonstrates the project's functionality and expected output.

Sample Output

You can refer to Part 7 for sample output examples.
