Solved Alternating Maps?

Hi, I have my maps stored in a config.yml, and it looks somewhat like this:

Code:

map1:
  x: 342
  y: -135
  z: 604
map2:
  x: -452
  y: -834
  z: 362
map3:
  x: 738
  y: -244
  z: 147

How in my plugin would I choose a random map? I have:

Code:java

Random random = new Random();
int mapNum = random.nextInt(/* how would I get the length of the maps in the config? */);

 

you could do this i suppose

*note*
may not be the best way to do this.

in your config do:

Code:

maps:
  map1:
    x: 342
    y: -135
    z: 604
  map2:
    x: -452
    y: -834
    z: 362
  map3:
    x: 738
    y: -244
    z: 147

then in code you can do.

Code:

ConfigurationSection mapSection = getConfig().getConfigurationSection("maps");
 
int mapCount = 0;
 
for(String maps : mapSection.getKeys(false)) {
 
mapCount++;
 
}
 
System.out.println(mapCount);

 

Code:java

Random r = new Random();
int mapNumber = r.nextInt(getConfig().getKeys(false).size())+1;
ConfigurationSection map = getConfig().getConfigurationSection("map"+mapNumber);
int x = map.getInt("x");
int y = map.getInt("y");
int z = map.getInt("z");

 

Ok, thanks ImDeJay and fireblast709 for the helpful replies!

Oh, just a quick question fireblast709 how would I do the random maps if I wanted my maps to have a specified name? Example:

Code:

maps:
  windmill:
    x: 342
    y: -135
    z: 604
  warehouse:
    x: -452
    y: -834
    z: 362
  office:
    x: 738
    y: -244
    z: 147

Code:java

Set<String> maps = getConfig().getConfigurationSection("maps").getKeys(false);
int r = new Random().nextInt(maps.size());
String map = maps.toArray(new String[0])[r];

 

Cool! Thanks Just a quick question, what does the .getKeys(false) do at the end?
