Reading multiple object serialization

[Henrique Boreg]

Hello, I am using object serialization to write objects to a file. Since I have lots of objects of the same type, I use a for loop:

try {
FileOutputStream fos = new FileOutputStream("test");
ObjectOutputStream oos = new ObjectOutputStream(fos);
 
for(Appointment appt : appointments) {
oos.writeObject(appt.getDate());
oos.writeObject(appt.getDescription());
}

oos.flush();
oos.close();
fos.close();
} catch(IOException e) {
e.printStackTrace();
}

This works fine, but how can I load all of these objects back again using the same loop approach, i tried the following:

(...)//initialize FileOutputStream, ObjectOutputStream, etc...
while((o = ois.readObject()) != null) {
GregorianCalendar date = (GregorianCalendar)o;
int length = ois.readInt();
String description = (String)ois.readObject();
}
ois.close();
fis.close();

This appears to work when I print out the results and they match the same values that were initially serialized, but I various Exceptions. What is the correct way to loop through all of the serialized objects until an EOF is reached?

Thanks.

Exactly which of the 'various exceptions' are you getting, and on which line(s)?

Its fixed now, the problem was an EOFException not being handled. Thanks anyways.
