   Basically I have a set of keys in a config, and I would like to randomly select one of them. The way I plan on going about doing this is counting how many keys there are in the config and selecting a random number from the amount of keys there are.
   
   This is what I have got so far, but I am not sure how I should proceed with the next part...
   

   Code:java

   int amount = pl.getCConfig("levels.yml").getKeys(false).size();
   int random = 1 + (int)(Math.random() * ((amount - 1) + 1));

   Any ideas?

   Code:java

   Set<String> keys = //code to get your keys
   int result = new Random().nextInt(keys.size());
   String key = (String) keys.toArray()[result];
