(I sent all the sample codes for this program in text so you can easily copy/paste them into the program to make it easier on you)
If you have any questions feel free to ask. Reminder: Follow the instructions in the images, create the classes using the sample codes I provided, adding some extra where needed, and complete the tasks for each class. I appreciate it. Thank you.
We are tasked with developing a system that represents a simple classroom grade tracking system. The My Simple Course System allows an instructor to manage Students and their Scores in a Course. Some major requirements are listed here: ● ● Each implemented class must be in separate file. Only the specified contractors should be included for the classes Score objects contains a name and a value (e.g Quiz1, 100). o The value cannot be less than 0.0 or more than 100.0. .. ● o The name cannot be null. Student objects contain name, id and an array of Score objects. o A student can have at most 10 scores (use an Array). o A Student objects can compute and return the average score of all its score objects. o The Student class can tell the number of Student objects instantiated. • The Course object can contain zero or more Student objects (use an ArrayList). The course can compute the average score of all the students' in the course.
Tasks - Score Class • Task 1: A Score object can be created by giving as an argument a name as a String, followed by a score as a double. Complete the method public Score(String scoreName, double score Val) to complete this task. See the method comments for more detail. • Task 2: The user will be able to ask for the value of a Score instance. The method will return the double representing the score's value. Complete the method public double getScoreValue() to complete this task. See the method comments for more detail. • Task 3: The user will be able ask for the name of a Score instance. The method will return the String representing the score's name. Complete the method public String getScoreName() to complete this task. See the method comments for more detail. • Task 4: The user will be able to set the value of the Score instance by giving a double as argument to the method. The method will return a boolean, true if the argument is at least 0.0 and no more than 100.0 and the value was updated in the Score instance. The method will return false if the argument is less than 0.0 or greater than 100.0 and the value will not be updated in the Score instance. Complete the method public boolean setScore Value (double score Val) to complete this task. See the method comments for more detail. ● Task 5: The user will be able to set the name of the Score instance by giving a String as argument to the method. The method will return a boolean, true if the argument is not null and the name was updated in the Score instance. The method will return false if the argument is null and the name will not be updated to the empty string in the Score instance. Complete the method public boolean setScoreName(String scoreName) to complete this task. See the method comments for more detail. • Task 6: The user will be able to ask for the textual representation of this Score instance. The method will return a String in the form specified in the example below. Complete the method public String toString() to complete this task. See the method comments for more detail. o Score [scoreName Quiz1, score Value-100.00] o Score [scoreName-Quiz23, score Value-22.33]
Tasks - Student Class • Task 1: A Student object can be created by giving as an argument a name as a String, followed by a ID as a int. Complete the method public Student(String stuName, int stulD) to complete this task. See the method comments for more detail. • Task 2: The user can add a Score object to the Student object by giving the Score object as an argument to the method. The method will return a boolean, true if the argument is not already in the Student's array and the array was updated in the Student instance and the count of Score objects in the array is incremented by 1. The method will return false if the argument is null or the Score object already exist in the Student's array and the array will not be updated in the Student instance. Complete the method public boolean AddScore(Score newScore) to complete this task. See the method comments for more detail. • Task 3: The user can update a Score object in the Student object by giving the Score name as a String and the new value as a double as argumenta to the method. The method will return a boolean, true if the Score object with that name is already in the Student's array and the array was updated with the new value in the Student instance. The method will return false if the name argument is null or the Score object does not exist in the Student's array and the array will not be updated in the Student instance. Complete the method public boolean update AScore(String scoreName, double newScore Val) to complete this task. See the method comments for more detail. • Task 4: The user will be able to ask for a specific Score's value by providing the score name as a String to the method. The method will return the double representing the score's value if a Score object with that name exist in the array. The method will return -1 if the argument is null or if the Score name does not exist in the array. Complete the method public double getAScore(String scoreName) to complete this task. See the method comments for more detail. • Task 5: The user will be able to ask for the average of all the Score object values in the array of the Student instance. The method will return the average as a double. Empty or null positions in the array should not be included in computing the average Complete the method public double computeMyAverage() to complete this task. See the method comments for more detail.
• Task 6: The user will be able to ask how many Student instances were created so far by calling the method. The method will return a int, the total number of Student instances.

Tasks - Course Class Task 1: The user can add a Student object to the Course instance by giving the Student object as an argument to the method. The method will return a boolean, true if the argument is not already in the Course's ArrayList and the ArrayList was updated in the Course instance. The method will return false if the argument is null or the Student object already exist in the Course's ArrayList and the ArrayList will not be updated in the Course instance. Complete the method public boolean addStudent(Student stu) to complete this task. See the method comments for more detail. • Task 2: The user can remove a Student object from the Course instance by giving the Student object as an argument to the method. The method will return a boolean, true if the argument is an existing Student object in the Course's ArrayList and the Student object was removed from the ArrayList in the Course instance. The method will return false if the argument is null or the Student object does not exist in the Course's ArrayList and the ArrayList will not be updated in the Course instance. Complete the method public boolean removeStudent(Student stu) to complete this task. See the method comments for more detail. • Task 3: [EXTRA CREDIT] The user can update a Student object in the Course instance by giving the updated Student object as an argument to the method. The method will return a boolean, true if the argument matches an existing Student object in the Course's ArrayList and the existing Student object was replaced by the argument in the ArrayList in the Course instance. The method will return false if the argument is null or the Student object does not exist in the Course's ArrayList and the ArrayList will not be updated in the Course instance. Complete the method public boolean update Student(Student stu) to complete this task. See the method comments for more detail. Task 4: The user will be able to ask for the average of all the Student objects in the Course instance. The method will ask each Student object for its' average of Scores and use that to compute the average of the course which will return the average as a double. Complete the method public double compute Course Average() to complete this task. See the method comments for more detail. • Task 5: Complete the get and set methods public ArrayList<Student getAllStudents(), public void setAllStudents (ArrayList<Student allStudents) to complete this task.
