java - Error when using ProtocolLibrary PacketAdapter() -

-

i making craftbukkit plugin has message in player count list, hive-mc or omega realm. coding in ecplise , using protocollib v3.2.0 , craftbukkit 1.7.2 r0.3. new java , don't understand much. know imported.

so far, here imported methods, code, , error

methods:

import java.io.file; import java.io.ioexception; import java.util.arraylist; import java.util.arrays; import java.util.list;  import org.bukkit.plugin.java.javaplugin;  import com.comphenix.protocol.packettype; import com.comphenix.protocol.protocollibrary; import com.comphenix.protocol.events.listeneroptions; import com.comphenix.protocol.events.listenerpriority; import com.comphenix.protocol.events.packetadapter; import com.comphenix.protocol.wrappers.wrappedgameprofile;

code:

    private list<wrappedgameprofile> message = new arraylist<wrappedgameprofile>();  public void onenable() {     if(!new file(getdatafolder(),"reset.file").exists()){         try {             getconfig().set("pcmessage",                     arrays.aslist(new string[]{"first line", "second line"}));             new file(getdatafolder(),"reset.file").createnewfile();         } catch (ioexception e) {             e.printstacktrace();         }      }        saveconfig();      (string str : getconfig().getstringlist("pcmessage"))         message.add(new wrappedgameprofile("1", str));        protocollibrary     .getprotocolmanager()     .addpacketlistener(             new packetadapter(                     this,listenerpriority.normal,             arrays.aslist(new packettype[] {packettype.status.server.out_server_info}),             new listeneroptions[] { listeneroptions.async })); {      } }

error:

cannot instantiate type packetadapter

as see in javadocs packetadapeter, declared as:

public abstract class packetadapter implements packetlistener

abstract means class not full class, , must implemented full class or anonymous class, cannot instantiated. need find subclass of packetadapter, or make 1 yourself.

for more information, see java tutorial abstract methods , classes.
