How to save the state of the program?

Question

Java

I am writing an application in javaFX + Spring.
During operation, one object is often used and modified, which is partially responsible for the state of the application. When the program is closed, this object must be saved and read when opened. how it is better and expedient to implement this by Serialization or XML, or another option?

Answer 1

Create XML, and parse it when the program starts, and if not, create and write basic properties.
