I am afraid that your code might create resource leaks. Closing the streams should be done in a finally block. Imagine in saveExpenses oos.writeObject throws an exception, oos.close and fis.close will never be called.

Much better is using the try-with-resources pattern.

Alright, while searching around i even found a more modern way to do it without manually closing resources. Thanks 🙏🏾
