Solved If config list is empty

I am making a team plugin. If every player from a team leaves I want the team to be deleted.

Some of my code:

Code:java

public String[] inteam = {};
getConfig().set("team." + args[1], Arrays.asList(inteam));

I have 2 questions:
How can I check if a config list is empty?
How can I delete a path and everything contained in the path within a config file?

1. This is how I typically do lists:

Code:java

    List<String> list = getConfig().getStringList("some string"); //define the list
    list.add(something) //add something to the list
    getConfig().set("some string", list); //set it in the config
    this.saveDefaultConfig(); //save the config
    this.reloadConfig(); //reload the config

2. Simply set it to null:

Code:java

getConfig().set("some string", null);

 

Any idea for how I can check if it's empty though? Would I just get the path and use an if statement for if it's equal to null?

Basically

Code:java

if (!(getConfig().getString("some string") == null){
//if the string isn't null, do something...
}else{
//do some stuff if it is null
}

 

Thanks!
