The following code produces an EOFException
. Why is that?
public static Info readInfoDataFromFile(Context context) {
Info InfoData = null;
FileInputStream fis = null;
ObjectInputStream ois = null;
Object object = null;
if (context.getFileStreamPath("InfoFile.dat").exists()) {
try {
fis = context.openFileInput("InfoFile.dat");
ois = new ObjectInputStream(fis);
Object temp;
try {
// here it throws EOF exception in while loop
while ((temp = ois.readObject()) != null) {
object = temp;
}
} catch (NullPointerException npe) {
npe.printStackTrace();
} catch (EOFException eof) {
eof.printStackTrace();
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (ois != null) {
ois.close();
}
} catch (IOException e) {
e.printStackTrace();
}
try {
if (fis != null) {
fis.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}

Depends on how many objects your file contains. If it has only one object, you can deserialise in one step.
try {
Object temp = ois.readObject();
}
catch(Exception e) {
//handle it
}
