Creating An Appointment Book

Hello! I am having trouble with this project. I have the main structure set up, but I am not sure how to implement events indefinitely, such as, the daily and monthly events. Also, the loading part is something I have not seen before, so I am not sure how to go about it. I would like to see a working code to edit my own code off of the working code. At the bottom is my failed coding efforts. Would love to see it edited and made nice or if you can do it better without doing that, I would appreciate it too!

Appointment Book class:

// Class Description: Stores Appointments into an array list
public class AppointmentBook {
   public static final String;
   public static final String DAILY = "Daily";
   public static final String MONTHLY = "Monthly";
   ArrayList<String> sApptList = new ArrayList<String>();

// Add appt to the string array list
String sAppt = "";

   public void addAppt(Appointment appt) {
       sAppt = appt.toString();
       sApptList.add(sAppt);
   }

   // Add loaded appts to new array list
   String sApptLoad = "";
   ArrayList<String> apptListLoad = new ArrayList<String>();

   public void addApptLoad(Appointment appt) {
       sApptLoad = appt.toString();
       apptListLoad.add(sApptLoad);
   }

// Saves the array list to a text file
PrintWriter writer;

   public void save(String string) {
       try {
           writer = new PrintWriter(new FileWriter(string + ".txt"));
           for (String str : sApptList) {
               writer.write(str);
           }
       } catch (IOException e) {
           e.printStackTrace();
       } finally {
           if (writer != null) {
               writer.close();
           }
       }
   }

   FileReader fileRead;

               txt = listReentry.get(1);
               sDate = listReentry.get(2);
               if (type.contains(" ")) {
                   type = type.replace(" ", "");
               }
               if (txt.contains(" ")) {

Appointment class:

import java.text.SimpleDateFormat;
import java.util.GregorianCalendar;

// Has to be of 3 subclasses
public abstract class Appointment extends AppointmentBook {
   /*
   * Variables:

   // textual description of event
   private String txt;
   // date of event
   private GregorianCalendar date;

   // Constructor:
   public Appointment(String txt, GregorianCalendar date) {
       this.txt = txt;
       this.date = date;
   }

   // Methods:
   // Test three different one before, after, and on given date
   public void occursOn(int year, int month, int day) {
       GregorianCalendar compDate = new GregorianCalendar(year, month, day);
       if (date.equals(compDate)) {
           System.out.println("The date is on the date given");
       } else if (compDate.after(date)) {
           System.out.println("The date is before the date given.");
       } else {
           System.out.println("The date is after the date given.");
       }
   }

   SimpleDateFormat f = new SimpleDateFormat("yyyy MM dd");
   String sDate = "";
   // toString method
   public String toString(){
       sDate = f.format(date.getTime());
       return " Description: " + txt + " Date Of Event: " + sDate;
   }

   // Getters and Setters:
   public String getTxt() {

   }

   public void setTxt(String txt) {

   public GregorianCalendar getDate() {
       return date;
   }

   public void setDate(GregorianCalendar date) {
       this.date = date;
   }
}

OneTime class(Monthly and Daily look the same just with monthly and daily variables instead because I do not know how to make them repeat indefinitely):

import java.util.GregorianCalendar;

public class OneTime extends Appointment {
   // Variables:
   GregorianCalendar GregorianCalendar();

   // Constructor:
   public OneTime(String type, String txt, GregorianCalendar date){
       super(txt, date);
       type = ONE_TIME;
   }

   // toString method
   String sType = "";
   public String toString(){
       sType = "One Time";
       return " Appointment Type: " + sType + super.toString();
   }
}

Tester class:

import java.util.GregorianCalendar;

public class Tester {

   public static void main(String[] args) {
       GregorianCalendar gDate = new GregorianCalendar();
       gDate.set(2017, 3, 10);
       AppointmentBook ab = new AppointmentBook();
       Monthly m1 = new Monthly("Monthly", "Workout", gDate);
       Daily d1 = new Daily("Daily", "Eat lunch", gDate);
       OneTime OneTime("One Time", "Skydiving", gDate);
       Monthly m2 = new Monthly("Monthly", "Visit grandma", gDate);
       Daily d2 = new Daily("Daily", "Sleep", gDate);

       ab.addAppt(m1);
       ab.addAppt(d1);
       ab.addAppt(one1);
       ab.addAppt(m2);
       ab.addAppt(d2);

       ab.save("appointments1");

       ab.load("appointments1");
       ab.getsApptLoad();

   }
}

If you have scrolled to the bottom and read this, thank you! You are the best person ever! I have no idea how to do this code :)

Project 1-75 points For this project we will be constructing an appointment book in an incremental fashion. It will be drawing on everything we have learned in the course thus far. You have some flexibility here in how you design this, so if you make any assumptions about the requirements, be sure to state them in your comments. This project is more independent than the Labs/Assignments. So, while the TAs and I are happy to help you with course concepts and requirements, we won't help you design or code for this project.
