how to write into a JSON file and what type of file should it be

Question

So for saving data, I am using a JSON file, I watched some tutorials and some people has a file ending with .js and the others .java. What should it look like? What type of a file should it be.

And if its a java file is it possible to write into it and edit it from a different class?

If anyone did this part and have any ideas please let me know :)

Maybe just hold off a few days -- I will help teams out with JSON in lecture!

Short version: make up your own file extension, like ".3dboard", but you'll still save it using a text file format.

We'll use the GSON library to read/write the data into JSON format.
