I am developing a GUI application that lets you add pieces of text to a note.txt.
The problem that I have is when I try to add a text it only adds a "0" and if you try to run the project it crashes. In the past it did not even recognise that the file even exist (somehow I got that fixed).

Figured out that the problem is here private void readAllNotes() class.

Would be grateful is someone could help.

here is my repository of the project on github, feel free to give advice on any part of the code.

public class AllNotes extends CommonCode 


ArrayList<Note> allNotes = new ArrayList<>();
private String crse = "";
private int maxID = 0;

AllNotes() 
 readAllNotes();


public final int getMaxID() 
 maxID++;
 return maxID;


private void readAllNotes() 
 ArrayList<String> readNotes = new ArrayList<>();

 readNotes = readTextFile(appDir + fileSeparator + "\Notes.txt");
 //System.out.println(readNotes.get(0));

 if (!"File not found".equals(readNotes.get(0))) 
 allNotes.clear();
 for (String str : readNotes) 
 String[] tmp = str.split("t");
 System.out.println(str);

 Note n = new Note();
 n.setNoteID(Integer.parseInt(tmp[0]));
 n.setCourse(tmp[1]);
 n.setDayte(tmp[2]);
 n.setNote(tmp[3]);

 allNotes.add(n);

 /*int nid = Integer.parseInt(tmp[0]);
 Note n = new Note(nid, tmp[1], tmp[2], tmp[3]);
 allNotes.add(n);

 if (nid > maxID) 
 maxID = nid;
 */

 
 
 maxID++;


public void addNote(int maxID, String course, String note) 
 Note myNote = new Note(maxID, course, note);
 allNotes.add(myNote);
 writeAllNotes();


public ArrayList<Note> getAllNotes() 
 return allNotes;


private void writeAllNotes() 
 String path = appDir + fileSeparator + "\Notes.txt";
 ArrayList<String> writeNote = new ArrayList<>();

 allNotes.stream().map((n) -> 
 String tmp = n.getNoteID() + "t";
 tmp += n.getCourse() + "t";
 tmp += n.getDayte() + "t";
 tmp += n.getNote();
 return tmp;
 ).forEachOrdered((tmp) -> 
 writeNote.add(tmp);
 );
 try 
 //FileWriter writer = new FileWriter("path");
 //BufferedWriter bw = new BufferedWriter(writer);
 writeTextFile(path, writeNote);
 catch (IOException e) 
 System.out.println("Problem! " + path);
 


public String searchAllNotesByKeyword(String noteList, int i, String s) 
 if (i == allNotes.size()) 
 return noteList;
 

 if (allNotes.get(i).getNote().contains(s)) 
 noteList += allNotes.get(i).getNote() + "n";
 

 return searchAllNotesByKeyword(noteList, i + 1, s);
