For the following program you will create 3 classes as seperate files. A course class a student class and a school class. You must write the body of each member function including constructors. When you are done write a client program that will test your school class. class course {public course(String n, int g) {} private String na; private int grade; public int getGrade(){} public String getName(){} } ***************************************** class Student { public student(String n){} final int MAX = 7; private String na; ArrayList<course> co = new ArrayList<course>(); public String getName(){} public double getAvg(){}; public void addCourse(String n,int g){} // use course constructor with array } ****************************************************************** class school { public school(){ } private ArrayList<Student> ar = new ArrayList<Student>(); public void printStudents(){} public void addStudent(String n){} // if room public void deleteStudent(String n) {} public void printStudentsAverages(){} // prints all students and averages public int findStudent(String n){} // returns index - -1 if not there public void addClass(String person, String classname, int g){} public boolean deleteClass(String person, String classname,int g){} }
