In this lab you will write a program to register students for courses. Your program will include classes for courses, the schedule of classes, student schedules, and times.

Course Class

Each Course object represents one course that is being offered. If there are multiple sections of a given course, then there will be a Course object for each section. To simplify things, we will assume that each course meets only once a week. The fields of the Course class are:

• name (String)
• number (String)
• number of credits (int)
• section number (int)
• department offering the course (String)
• day of the week that the Course meets (String)
• start time of the class (Time)
• end time of the class (Time)
• number of students registered (int)
• maximum number of students allowed (int)

The methods of the Course class are:

• default constructor (does nothing)
• constructor to initialize all fields (pass Strings, ints, and Times as the parameters)
• printAll (print out all the Course information in a nice format, also print whether the course is open or closed)
• print (using a nice format, print out the name, number, section, credits, date, start time, and end time)
• addStudent (add a student to the course if there is room, and return true if added, false if course was already full)
• removeStudent (if there is at least one student registered, remove one and return true, otherwise return false)
• some other small methods will probably be needed

ClassSchedule Class

A ClassSchedule object holds the schedule of classes for a single semester -- this is the list of all classes that are being offered. The fields of the ClassSchedule class are:

• semester (String -- example: "Spring 2000" or "Summer 2000")
• list of courses being offered (Vector)

The methods of the ClassSchedule class are:

• default constructor (set semester to "Spring 2000" and initialize the list of courses to empty)
• constructor with one String parm (set semester to the parm and initialize the list of courses to empty)
• add (parm is a Course object; add a Course to the schedule -- if the course and section isn't in the schedule, add it and return true; otherwise return false)
• print (print all Courses in the schedule)
• listByName (parm is a String for the course name; print all Courses in the schedule which match the course name given in the parm)
• listByDept (parm is a String for the department name; print all Courses in the schedule which are offered by the department given in the parm)
• getCourse (parms are course name and section number; return the Course object in the schedule which matches the given name and section number)

StudentSchedule Class

A StudentSchedule object holds the schedule of a particular student. There will be one StudentSchedule object for each student that is registering for courses.The fields of the StudentSchedule class are:

• student name (String)
• student number (String)
• number of credits for the current semester (int)
• list of Courses on the student's schedule (Vector)

The methods of the StudentSchedule class are:

• default constructor (initialize the credits to 0 and the list of courses to empty)
• constructor with parms for the student name and number (initialize the name and number from the parms, initialize the credits to 0 and the list of courses to empty)
• addCourse (parm is the Course to add; if there is room in the course, then add the student to the Course, add the Course to the student's schedule, and return true; otherwise return false)
• dropCourse (parm is the name of the Course; if the student is registered for the Course, then remove the student from the Course, remove the Course from the student's schedule, and return true; otherwise return false)
• print (print the student's schedule, use the print method of Course)

Time Class

You will need a Time class to hold and print the start and end times of Courses. Remember that when we are talking about classes, we work with only hours and minutes. The fields of the Time class are:

• hours, minutes, and seconds (each is an int)
• AM/PM flag (you can represent this however you want)

The methods of the Time class are:

• default constructor (initialize to some default time)
• constructor with parms for all the fields (initialize the Time to the given values)
• toString (return a String for the Time in the format hh:mm:ss AM or PM)
• toStringNoSecs (return a String for the Time in the format hh:mm AM or PM)
