Socket-based upload/download (Java) Lite version

In a simple example, there is no interface but code.

Server code

Package server; import Java. io. bufferedinputstream; import Java. io. bufferedoutputstream; import Java. io. datainputstream; import Java. io. dataoutputstream; import Java. io. fileinputstream; import java.net. serversocket; import java.net. socket; public class androidserver implements runnable {private serversocket = NULL; private datainputstream is; Public void run () {If (serversocket = NULL) {try {se Rversocket = new serversocket (5926);} catch (exception e) {e. printstacktrace () ;}try {Socket socket = serversocket. accept (); is = new datainputstream (New bufferedinputstream (New fileinputstream ("D: \ test.mp4"); // upload the file to be uploaded, put inputstreamdataoutputstream OS = new dataoutputstream (New bufferedoutputstream (socket. getoutputstream (); // initialize the socket outputstreamint count; byte [] buffer = new byte [1024]; W Hile (COUNT = is.
