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() {} 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; private int ct =0; // how many courses private course [] courses = new course[MAX]; // each student has up to 7 courses public String getName(){} public double getAvg(){}; public void addCourse(String n,int g){} // use course constructor with array } ****************************************************************************** class school { public school() {ct = 0; } final int MAX = 20; private int ct; // number of students in school private student [] ar = new student[MAX]; 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(int n, String na, int g){} // add a class for person at index n }
