How to write and read a .yml file?

I'm working on a plugin right now but i need to write and read to a groups.yml file, i searched a long time but everything i tried didn't work.

I really wanna go further with the plugin but i can't i first need the groups.yml file.

 

If you're talking about developing a plugin, you're in the wrong section. The correct section where you would receive more attention is here.

You posted in the section where users ask other users for tips and help on their Bukkit server.

Thread has been alerted to the staff for a move.

 

Moved to Plugin Development.

 

Have you tried looking at the wonderful wiki we have?
I guess not, since that would've answered your question.

 

yes i have but i couldn't find it can you than send a link?

 

http://wiki.bukkit.org/Configuration_API_Reference

 

Thanks but it is only config how do i add an extra file like groups.yml

 

Why don't you just use java file I/O operations?

 

I already made it and it works the only thing is that when i reload it it's empty do you mabey know how to fix it?

 

u need to save the file like u do for the config with saveConfig()

i created a copy of the default Config.java and edit this to work with custom yml files ... maybe its helpfull for u ...
