Class 1 Student.

• Static Variables
  • private static int nextID=0;
• Instance Variables
  • int id
  • String name
  • ArrayList<String> currentCourses
  • ArrayList<String> priorCourses
  • ArrayList<Double> currentGrades
  • ArrayList<Double> priorGrades
• Constructors
  • no default constructor
  • public Student(String name, int a)
    • //these parameters initialize nameand age, respectively
    • make sure that you initialize the other instance variables appropriately
    • assign each student a unique id
• Accesor Methods
  • public int getId() //returns a student's id
  • public String getName() //@returns the concatenation ofname
  • public void printCourses() //this prints a comma separated list of each course and its corresponding current grade. Output might look so meting like:
    • "English: 88, Math: 77, History " 91"
  • public void dropClass(String courseTitle) //this remove courseTitle from currentCourses and it also removes its corresponding grade from currentGrades.
  • public void updateGrade(String course, double grade) //
  • public double getTermAve() //returns the average of your current courses
  • public double getCumulative() //returns the average of all prior courses
  • public String toString() //follows conventions of the toString() method
  • boolean equals(Student other) //returns true if other has the same id
  • public int compareTo(Student other ) //returns the difference between this object and other's cumulative average
• Mutator Methods
  • public void addCourse(String course) //@ adds course to currentCourses and adds -1 to currentGrades
  • public void dropOut() // clears currentCourses and currentGrades
  • public void graduate() // calls completeTerm() and sets the currentCourses and currentGrades to null
  • public void completeTerm()//
    • This method is called upon completion of the current semester. Therefore all of the currentCourses should be added to priorCourses.
    • currentCourses should be reset to an empty ArrayList
    • Do the same thing with currentGrades and priorGrades.
    • Also, you should update cumulativeAverage and set currentAverage to -1
• Other Methods
  • public Student clone()// this returns a new Student that is a clone of the current student. Ie all of the data for the cloned student should the same

Class 2 School.

• Static Variables
  • private static int nextID =0;
• Instance Variables
  • private String districtName
  private int schoolId
  • private ArrayList<Student> studentBody
• Constructors
  • public School( )
    • initialize instance variables and assign school a unique id
• Accesor Methods
  • public int getStudents() //returns the number of students in school
  • public ArrayList<Student> getStudents() ; //returns studentBody
  • public double getMean(int gradeLevel) //this returns average of all students whose gradeLevel is grade
  • public ArrayList<Student> getStudentByName(String name) //returns an ArrayList of Students whose names match the paramaters
  • public Student getStudentById(int studentId) //returns the student whose id is id
  • public String toString() //you know the deal
  • public boolean equals(School s) // returns true if the schools id is equal
  • public int compareTo(School other) //returns the difference (as an int) between the number of students in this object and other
  • public ArrayList<Student> getHonorRoll() //returns an arraylist of student's whose cumulative average is at least 90.
  • ** Extra Credit
    • 1) add a compareTo method to the student class that compares their cumulative averages
    • 2) add the following method to School
      • ArrayList<Student> sort() //this method returns the student body ordered by their cumulative average. Note: You must use the student method compareTo() to do this. Also, you may not use any helper utility methods to complete this method. Among other things ( Stella) , you may not use any of the static methods of the Collections or Arrays classes.
• Mutator Methods
  • public void addStudent(Student s) //adds s to studentBody
  • public void dropStudent(Student s)//removes student from studentBody
  • public void dropStudent(String first, String name)//removes student from studentBody
