Trouble streaming objects to file

[Jason Rod]

I am trying to stream an arrayList from another class and write it to file. The code has no errors but nothing is being written to the file either. The file name is "Accounts.txt". Here is the code:

 package bank;
 
import java.io.*;
import java.util.*;
import javax.swing.*;
 
public class LoadStoreAccounts {

//main constructor
public LoadStoreAccounts() {}

public static ArrayList readCollectionObject(ArrayList accountList){
try {
FileInputStream inObject = new FileInputStream("Accounts.txt");
ObjectInputStream inObj = new ObjectInputStream(inObject);

ArrayList anAL = (ArrayList) inObj.readObject();
inObj.close();
return anAL;
}

catch(Exception e) {
e.printStackTrace();
return null;
}
}

public static void writeCollectionObject(ArrayList accountList) {
try {
FileOutputStream outObject2 = new FileOutputStream("Accounts.txt");
ObjectOutputStream outObj2 = new ObjectOutputStream(outObject2);

outObj2.writeObject(accountList);
outObj2.close();
JOptionPane.showMessageDialog(null, "New account has been saved to disk");
}

catch(Exception e) {
e.printStackTrace();
}
}
 
}   

I don't know if that code is even right, but any help would be greatly appreciated. Thanks in advance.

Is the file actually created and empty? Or won't it even just be created? Do you also know where the file actually would be written? (the system path).

Problem solved, found out that my problem was with the .txt file I was trying to write to, Thanks for the response though.
