metrics error

im getting this error in eclipse that says "cannot resolve length" on line "players"

// Construct the post data
final StringBuilder data = new StringBuilder();
data.append(encode("guid")).append('=').append(encode(guid));
encodeDataPair(data, "version", description.getVersion());
encodeDataPair(data, "server", Bukkit.getVersion());
encodeDataPair(data, "players", Integer.toString(Bukkit.getServer().getOnlinePlayers().length));
encodeDataPair(data, "revision", String.valueOf(REVISION));

have no idea how to resolve this.....

before anyone starts flaming me i am a noob at this and am trying to learn as fast as i can but i could really use some help.

 

@Echen_kraul That's because #getOnlinePlayers() doesn't return an Array. To get the amount of players online, just use #getOnlinePlayer().size()

 

.length is for arrays. Without checking I'm pretty sure Server#getOnlinePlayers() returns a List, which isn't an array. To access it, use List<?>#size()

 

it worked ... thanks alot
