java - 为什么找不到getInputStream？

Question

我有这个代码:

ServerSocket serverSideSocket = new ServerSocket(1234);
        serverSideSocket.accept();
        BufferedReader in = new BufferedReader(new InputStreamReader(serverSideSocket.getInputStream()));

编译器告诉我它找不到“getInputStream”。我不懂为什么。在代码的开头，我导入 java.net.*.

Answer 1

调用accept会返回Socket的实例，该实例具有所需的方法getInputStream。

代码可能如下所示:

ServerSocket serverSideSocket = new ServerSocket(1234);
Socket socket = serverSideSocket.accept();
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
