config.yml - Lists, and getting their values?

    So, recently I've been working on this waypoints plugin. It includes a config.yml file where server owners can create server waypoints (like spawn, or a shop) and specify their x-coordinate, y-coordinate, and z-coordinate. I'm not a 100% pro with java though. So, I have my config.yml:

    - Spawn:
    - x: 0
    - y: 50
    - z: 0
    - name: Spawn

    Sorry, I don't really know how to put this in a code block :/ - Anyways right now what I'm trying to do is loop through my waypoints. I've been trying to get the name of the waypoint it's currently looping through but I'm not sure how to. Code:

    for (int i = 0; i > plugin.getConfig().getList("waypoints").size(); i++) {
                ItemStack newItem = new ItemStack(Material.BEACON); // Ignore this
                ItemMeta newItemMeta = newItem.getItemMeta(); // Ignore this
                newItemMeta.setDisplayName(ChatColor.DARK_PURPLE + plugin.getConfig().getList("waypoints."); // So right here is where I want to get the name of the waypoint it's currently at in the for loop. I'm confused with config.yml files though, and how java interprets lists.
    Thanks! Any help is appreciated! :D

    Alright, so I went ahead and did:
    String waypointName = plugin.getConfig().getList("waypoints").get(0).toString();
    Bukkit.getServer().broadcastMessage(ChatColor.GREEN + waypointName);
    That gives me:
    {Spawn=[{x=0}, {y=50}, {z=0}, {name=Spawn}]}
    So, how can I access name?

    It doesn't really make sense to store the waypoint name twice in the config..
    You can get the name of each waypoint by looping through config.getConfigurationSection("waypoints").getKeys(false)

    For example your config looks like this:
    Then the method above will return a list containing "spawn" and "shop"

    Ok, so I setup the config file as you stated (by removing "- name: Spawn") although, how can I get the name of each item in the list?

    So you provided me with the code to get a list. Can I do:

    getConfig().getConfigurationSection("waypoints").getKeys(false).get(0) // To get what's in the 0th position in the list?

    Also, I need to access X, Y, and Z values eventually so how could I also do that?

    This is how you would structure your config.yml:
        X: 1
        Y: 1
        Z: 1
        X: 5
        Y: 5
        Z: 5
    You need to use the getConfig().getConfigurationSection("waypoints").getKeys(false); to get a list of all the warps.
    Say you wanted to use a command to warp, you would do this: getConfig().getDouble("waypoints."+args[0]+"X"); and so on for y and z values. Add a check to make sure all the values exist.
    You would then teleport the sender to those x,y and z location.

    This is exactly the explanation I was looking for. Thank you very much! Also, after args[0] inside of the string that's being concatenated wouldn't you add a "." before the "X"? Maybe I'm wrong, but that's how it seems it should be done. Anyways, thanks once again! :D Gonna go test it now!

    I actually have another issue now... When I do:

    plugin.getConfig().getConfigurationSection("waypoints").getKeys(false)[0] // It says I can't, because it should be an array but it's resolved to Set<String>. Solution?

    @mccrafter1212 yeah, you need to use a dot before the 'X'.
    I don't know why the getKeys() method didn't work for you.
    @timtower Some advice?
