Socket Sample Code demo program (threaded)

Client code, such as the following:

Import Java.io.*;import java.net.*;p ublic class Dailyadviceclient {public void Go () {try {socket s=new socket ("127.0.0.1" , 4242);//Establish a socket connection to the server//client read data from the server//establish a inputstreamreader//to connect to the low-level input stream on the socket InputStreamReader is a bridge between the lower and upper streams//s.getinputstream () gets the input stream from the socket InputStreamReader streamreader=new InputStreamReader (S.getinputstream ());//build BufferedReader to read BufferedReader reader=new BufferedReader (streamReader ); String Advicestring=reader.readline (); System.out.println ("Today You should:" +advicestring);//client sends data to the server//creates PrintWriter objects without their own active row refreshes. Assuming that the second parameter is added to True, the active refresh for itself does not need to write Writer.flush () This line of code PrintWriter writer=new PrintWriter (S.getoutputstream ()); Writer.println ("Hello,i am client2!"); Writer.flush ();//Flush Send data System.out.println ("Remote address for this socket connection:" +s.getinetaddress (). gethostaddress ()); SYSTEM.OUT.PRINTLN ("Local address of this socket binding:" +s.getlocaladdress (). gethostaddress ()); SYSTEM.OUT.PRINTLN ("Local port for this socket binding:" +s.getlocalport ()); SYSTEM.OUT.PRINTLN ("The remote port this socket is connected to:" +s.getport ()); S.close ();//Close Socket} catch (ioexceptIon e) {//TODO auto-generated catch Blocke.printstacktrace ();}} public static void Main (String[]args) {dailyadviceclient client=new dailyadviceclient (); Client.go ();}}

Server-side code such as the following:

Import Java.io.*;import java.net.*;p ublic class Dailyadviceserver {string[] advicelist={"Take smaller Bites", "one word: Inappropriate "," "+" Just for today,be Honest "," Tell Your Boss "};p ublic void Go () {try {//server application creates a ServerSocket object for a specific port This causes the server application to listen for client requests from 4242port ServerSocket serversocket=new serversocket (4242);//the server enters an infinite loop waiting for the client's request while ( true) {System.out.println ("Wait for Client connection ...");//After receiving a user connection request.
