Tor appears to client applications as a SOCKS proxy.  Sun's JDK can
speak SOCKS out of the box if you set the system properties
socksProxyHost and socksProxyPort.

So I believe that your Java application will automatically go through
tor if you do

  java -DsocksProxyHost=localhost -DsocksProxyPort=9050 AlicesRestaurant

Alternatively, you could modify your application to explicitly use
a SOCKS proxy by creating your sockets as so:

  new Socket(new Proxy(Proxy.Type.SOCKS,
                       new InetSocketAddress("127.0.0.1", 9050)));

Note however that Java most probably implements SOCKS with IP
addresses, and unless you take special precautions, you will suffer
from DNS leaks.  Which may or may not be a problem for your application.
