创建循环通用引用

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);
