How do you store attributes for a java text file in the file itself?

[GoodbyeWorld]

I was thinking of using the UserDefinedFileAttribute class and stuff to do this, but I don't know if what I want is even possible.

Can you store attributes such as Font and text color and stuff inside a .txt file itself?

If another text program that opens the file you made or modified inside such an editor, will it ruin the attributes and set them to null?

(i.e. if I pull this off in a java notepad, if I ever opened the file that had the attributes with some other editor such as Windows Notepad, would the other editor mess with the attributes, hence possibly ruining them?)

The UserDefinedFileAttribute route involves a lot of strange interfaces (ones I don't have a clue what they do) and I'm wondering if I'm going the wrong route.

if you want to save the state of an object you can make the class implement Serializable and then save using ObjectOuputStream.

It may have many different properties. I'm not sure if I should be focusing on it as a "property" or as a "state".

How would this info be saved in the file, and hence be able to be read in as an attribute of the file/document (it has to be stored in an actual file or as an attribute that can be accessed from the File object, which could already exist and need not be created anew every time) and applied to the JTextArea in a notepad? I mean, how would you store a font of a JTextArea as a file (which contains the text in the JTextArea) and then read that font attribute and use that read attribute to set the font when the file is loaded up?

Any ideas?
