How to use the server pinger

The MinecraftServerPinger class it's very easy to use, it will manage everything for you, SRV domain resolve, offline check, getting server's data, connection timeout management...

Here is an example for you:

MinecraftServerStatus server = MinecraftServerPinger.ping("serveradress.com:25544");
// In case the server is not online:
if(server.isOffline()) {
   System.out.println("Minecraft server 'serveradress.com' is not online!");

   // You can get the server connection exception like that:
   OfflineMinecraftServerStatus offlineServer = (OfflineMinecraftServerStatus) server;
   offlineServer.getException().printStackTrace();
   return;
}

// These methods will throw an exceptions in case the server is not online.
String motd = server.getMotd();
long latency = server.getPing();
Version version = server.getVersion();
Players players = server.getPlayers();
String base64Favicon = server.getFavicon();

Additional utilities

Advanced server query mode

If you want to have a little more control of this process you can use the MinecraftServerConnection class. You will need to provide a InetSocketAddress and optionally a connection timeout time in milliseconds.

Here is an example:

InetSocketAddress socketAddress = new InetSocketAddress("serveradress.com", 25565);

MinecraftServerConnection connection = new MinecraftServerConnection(socketAddress);
connection.setTimeout(5000); // Optional timeout (default was 1000ms)
MinecraftServerStatus server = connection.fetchData();

// Here you can continue as the first example. (isOffline(), getMotd()...)

SRVResolver resolver

Some minecraft servers uses SRV domain records to manage server's port. With the SRVResolver utility class, you can obtian the server real domain and port.

InetSocketAddress address = SRVResolver.getSocketAddress(serverAddress);
String serverAddress = address.getHostName();
int serverPort = address.getPort();
