Write after close: 如果在调用了 socket.close() 之后尝试写入数据,会引发该错误。 2.1 处理写入错误 处理写入错误最好的方式是通过以下几种方式进行异常捕获和处理。可以尝试重试操作,记录日志,或者优雅地关闭 socket。 try{out.println("This is a test message");}catch(SocketExceptione){System.err.println("...

Open a socket. Open an input stream and output stream to the socket. Read from and write to the stream according to the server's protocol. Close the streams. Close the socket. Only step 3 differs from client to client, depending on the server. The other steps remain largely the same....

Step 3 is encoded in thewhileloop. As long as the client and server still have something to say to each other, the server reads from and writes to the socket, sending messages back and forth between the client and the server. The server initiated the conversation with a "Knock! Knock!
