循环通用引用确实是可能的。Java泛型和集合包括几个示例。对于您的情况，这样的标本应如下所示：
public interface P2PNetwork<N extends P2PNetwork<N, C>, C extends P2PClient<N, C>> { void addClient(C client);}public interface P2PClient<N extends P2PNetwork<N, C>, C extends P2PClient<N, C>> { void setNetwork(N network);}class TorrentNetwork implements P2PNetwork<TorrentNetwork, TorrentClient> { @Override public void addClient(TorrentClient client) { ... }}class TorrentClient implements P2PClient<TorrentNetwork, TorrentClient> { @Override public void setNetwork(TorrentNetwork network) { ... }}...TorrentNetwork network = new TorrentNetwork();TorrentClient client = new TorrentClient();network.addClient(client);
