Java Learning note--socket for file transfer

The more I flee, the closer I get to you.

The more I recite my face, the more I see you.

I started from you,

I'm at your end.

Requirement: Implement socket transfer file under LAN.

Client steps:

1, establish a connection with the server

2. Create client output stream

3. Create an input stream and bind the file

4. Output to the server after reading the file

Server-Side steps:

1. Start the server

2. Create the Accept input stream

3. Create an output stream to bind the file

4. Read client information to local file

1. Byte stream transfer file.

1  Public classClient {2 3      Public Static voidMain (string[] args) throws IOException {4Socket client =NewSocket ("192.168.0.112",50000);5OutputStream OS =Client.getoutputstream ();6FileInputStream FIS =NewFileInputStream ("/home/yanshaochen/public/2017-05-06 15-12-02 screen. png");7         byte[] bytes =New byte[1024x768];8         intdata;9          while(data = fis.read (bytes))! =-1){TenOs.write (Bytes,0, data); One         } A fis.close (); - client.close (); -System. out. println ("sent successfully!"); the     } -}

1  Public classServer {2 3      Public Static voidMain (string[] args) throws Exception {4ServerSocket Server =NewServerSocket (50000);5System. out. println ("listening .");6Socket Accept =server.accept ();7InputStream is=Accept.getinputstream ();8FileOutputStream fos =NewFileOutputStream ("d:\\download\\ screen. png");9         byte[] bytes =New byte[1024x768];Ten         intdata; One          while(data = is. Read (bytes))!=-1){ AFos.write (Bytes,0, data); -         } - fos.close (); the server.close (); -}

2. Character stream transfer file txt.

1  Public classClient {2 3      Public Static voidMain (string[] args) throws IOException {4         5Socket client =NewSocket ("192.168.0.112",50000);6OutputStream OS =Client.getoutputstream ();7Reader FR =NewFileReader ("/home/yanshaochen/public/zfsm.txt");8BufferedReader br =NewBufferedReader (FR);9 String buffer;Ten          while(buffer = Br.readline ())! =NULL){ OneBuffer + ="\ r \ n"; A Os.write (Buffer.getbytes ()); -         } - br.close (); the client.close (); -System. out. println ("sent successfully!"); -     } -}

1  Public classServer {2 3      Public Static voidMain (string[] args) throws Exception {4 5ServerSocket Server =NewServerSocket (50000);6System. out. println ("listening .");7Socket Accept =server.accept ();8InputStream is=Accept.getinputstream ();9FileWriter FW =NewFileWriter ("D:\\download\\zfsm.txt");Ten         byte[] bytes =New byte[1024x768]; One         intdata; A          while(data = is. Read (bytes))! =-1){ -Fw.write (NewString (Bytes,0, data)); -         } the fw.close (); - server.close (); -     } -  +}
