Loading data from a YAML configuration

Once the save method is completed, we are ready to write the load method. We are already familiar with loading data using the Bukkit configuration API. We have done so in the previous chapter when we retrieved values from config.yml. This will be very similar. However, we must first manually load the configuration using the following code, which will be different. We should only do this if the file actually exists. The file will not exist the first time that the plugin is used, so we do not want an error to occur in that situation.

File file = new File(plugin.getDataFolder(), "warps.yml");
