Question

I'm having some trouble deserializing a file that I previously created by serializing, everything is working fine until this point...I can't figure out what I'm doing wrong...

Answer 1

This is the method so far
```
//deserialize from file created by serializeToDisk
public static ArrayList<Fruit> fromSerialized(
String fileInput, ArrayList<Fruit> newFruitDetails) {
FileInputStream fis;
try {
fis = new FileInputStream(fileInput);
ObjectInputStream ois = new ObjectInputStream(fis);
newFruitDetails = (ArrayList<Fruit>) ois.readObject();
ois.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return newFruitDetails;
}

Answer 2

Just guessing what could be wrong, maybe class Fruit or superclasses don't implement Serializable, or .ser file extensions aren't being used, or something else.

On a side note, it's missing a `fis.close();`

Answer 3

What is or isn't happening with this code?

Answer 4

The superclass, Grocery, implements Serializable so I didn't make the fruit class implement Serializable.

The file being deserialized wasn't a .ser file. I fixed that.

I added the `fis.close();`

but an arrayList still isn't being made.

Answer 5

okay, my bad method is working, I just wasn't calling the displayFruits() method right, so I couldn't see the results

Thanks
