Help saving values to Config.yml!

Hello guys!
I'm a bit more experienced Java Programmer, and currently messing around with Plugin ideas.
The most of them need to save values, so I thought about saving them to a config.yml .
For example, I want to save the score (an Integer value, which is handled and managed by the plugin) of all players that joined the server so far.

But how do I do this? I understood most of the things in the API, but I don't really know how and when to use saveConfig(), saveDefaultConfig(), reloadConfig(), and which file JavaPlugin.getConfig() returns, the file in the data folder, or the one in the jar?

Thanks for your help!

 

save config should work.

this might help; its from stuntguy3000 and coastermans10's annihilation plugin

Code:java

public void setValue(StatType s, Player p, int value) {
        if (!plugin.useMysql) {
            config.getConfig("stats.yml").set(p.getName() + "." + s.name(),
                    value);
            config.save("stats.yml");
        } else {
            plugin.getDatabaseHandler().query(
                    "UPDATE `" + plugin.mysqlName + "` SET `" + s.name().toLowerCase()
                            + "`='" + value + "' WHERE `username`='"
                            + p.getName() + "';");
        }
    }
