Whats the best way to store nested Lists (lists inside of lists)?

How can I save lists that I have lists in a flat file and recall them later? I am trying to have one array list of locations for each player inside of one big list to keep everything organized. Do I need to find another way to do it? Are there going to be issues? I am currently using the default Bukkit configuration features.


Thanks in advance!

 

Two-Dimnesional Arrays?
/Blame me if it's not what you're looking for/

 

Well yeah that's what I'm looking for essentially and I know how to use them but what I really want to know is how to save them in a text file and then recover them easily later.

 

Well, i think you'll need to make for, and then save them, let's wait for someone's else opinion.

 

Ok thanks for the help anyway!

 

Well there is no standard way, you just have to write your own way to save and load them based on your own personal preference.

How I would do it is save it like so:

Code:

{
1[1],1[2],1[3],
2[1],2[2],2[3].
}

Where the first value is the first dimension of the array and the value inside the brackets is the second dimension of the array. After that is just reading all the values and figuring out how much memory to allocate and what goes where.

 

The Configuration API should be able to have a path set to l and written out.
for example
let l be of type List<List<? extends ConfigurationSerializable>>

Code:

getConfig().set("list", l);

 

Wouldn't setting the value l (assuming it is a list in this case) attempt to save the name of it and not the actual values?

 

No, collections should be written with the value. In this case a List of a List of ConfigurationSerializable items.

 

Well thanks. These are the ways I was planning to do this. I thought there might be a different way but that sounds good. Thanks for the quick replies!
