Унаследование в классе

Есть клас унаследованый от веб сокет сервера, выглядит примерно так.

public class SimpleServer extends WebSocketServer {
    public SimpleServer(InetSocketAddress address) {
        super(address);
    }
    @Override
    public void onOpen(WebSocket conn, ClientHandshake handshake) {
        conn.send("Welcome to the server!"); //This method sends a message to the new client
        broadcast( "new connection: " + handshake.getResourceDescriptor() ); //This method sends a message to all clients connected
        System.out.println("new connection to " + conn.getRemoteSocketAddress());

    }
    @Override
    public void onClose(WebSocket conn, int code, String reason, boolean remote) {
        System.out.println("closed " + conn.getRemoteSocketAddress() + " with exit code " + code + " additional info: " + reason);
    }
    @Override
    public void onMessage(WebSocket conn, String message) {
        System.out.println("received message from " + conn.getRemoteSocketAddress() + ": " + message);
    }
    @Override
    public void onMessage( WebSocket conn, ByteBuffer message ) {
        System.out.println("received ByteBuffer from "  + conn.getRemoteSocketAddress());
    }
    @Override
    public void onError(WebSocket conn, Exception ex) {
        System.err.println("an error occured on connection " + conn.getRemoteSocketAddress()  + ":" + ex);
    }
    @Override
    public void onStart() {
        System.out.println("server started successfully");


    }
}

и все хорошо но что если я хочу разместить содержимое этого класса в MainActivity который унаследован от AppCompatActivity ?
