Can I wrote an object to files and later on retrieves it with its integrety intact? Is there a ready made function or do I have to write one?

I am new to Java, is this what one calls serialization?

yes, that's serialization.
It works if you take some basic precautions (like making sure every field in your class is itself Serializable or transient).

Of course you should mark things that rely on external data as being transient so they don't get serialized as those external resources likely will not exist or be different when you deserialize it again.

Thank yo so much! I need to study this more.

Try using ObjectInputStream and ObjectOutputStream.
