I'm not sure what happened when saving a file, but now when I try to load it I get java.io.EOFException. All of the code is in try/catch blocks but there was no error when saving the file.
Opening the file:
FileInputStream fileInputStream = new FileInputStream(file);
ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
ArrayList<Tournament> allTournaments = (ArrayList<Tournament>) objectInputStream.readObject();
objectInputStream.close();
fileInputStream.close();
The file is an ArrayList of Tournament objects
I need to be able to repair the file and access the data. I've been searching for a way to read the file Tournament by Tournament saving each one into another Arraylist but I haven't been able to find anything useful.
Is this possible?
The file was saved with:
File f = new File(path);
FileOutputStream out = new FileOutputStream(f);
ObjectOutputStream objectOutputStream = new ObjectOutputStream(out);
objectOutputStream.writeObject(gm.getTournamentList());
objectOutputStream.close();
out.close();
Thanks

Edit: When I run this code I can see the data as a String so it appears the data is fine. I just need some similar piece of code that will go Arraylist item to Arraylist item instead of line by line.
try (BufferedReader reader = new BufferedReader(newFileReader(file.getAbsolutePath()))) {
String line;
while ((line = reader.readLine()) != null) {
}
} catch (IOException e) {
e.printStackTrace();
}
throws IOExceptionis better, for example.
