昨天到34关了，今天怎么又得从第一关开始了😰

抽奖

摸鱼结束，开始工作😭我正在参加码神挑战，一起呀~https://1024.codefather.cn/

这题什么意思？也没给参数呀

看了一会评论区，感觉有些题不止一个答案呀🧐

大佬们给个思路，真想不出来了😢

第四关炸鱼皮我跟你拼了😡

#提问# 因为时间比较紧，所以没学前端，用鱼总的项目去面试的话，会被问前端的问题吗？如果被问到说和同学合作的，我只负责后端部分可以吗？

#提问# socket编程的IO流关闭顺序是什么？这是我的服务端代码和客户端代码，此时可以正常运行。但是将服务端的bis.close();放到bos.close();后面就会报错：Socket is closed。更改客户端的bos.close();的位置也会导致Socket is closed。是服务端和客户端之间的IO流只能在最后一起关闭吗？ public class TCPFileUploadServer { public static void main(String[] args) throws IOException { ServerSocket serverSocket = new ServerSocket(9999); Socket socket = serverSocket.accept(); String file_path = "tarimg\\2.jpg"; BufferedInputStream bis = new BufferedInputStream(socket.getInputStream()); BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file_path)); int readLen = 0; byte[] buf = new byte[1024]; while((readLen = bis.read(buf))!=-1){ bos.write(buf,0,readLen); } bos.flush(); bos.close(); BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())); bw.write("收到图片"); bw.newLine(); bw.flush(); socket.shutdownOutput(); bw.close(); bis.close(); socket.close(); serverSocket.close(); System.out.println("已发送"); } } public class TCPFileUploadClient { public static void main(String[] args) throws IOException { Socket socket = new Socket(InetAddress.getLocalHost(),9999); String file_path = "srcimg\\1.jpg"; BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file_path)); BufferedOutputStream bos = new BufferedOutputStream(socket.getOutputStream()); byte[] buf = new byte[1024]; int readLen = 0; while((readLen = bis.read(buf))!=-1){ bos.write(buf,0,readLen); } bos.flush(); bis.close(); socket.shutdownOutput(); BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream())); String s = br.readLine(); System.out.println(s); br.close(); bos.close(); socket.close(); } }
