一,服务端:
package com.samael.socket;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import .ServerSocket;
import .Socket;
public class MyServer {
class ThGetMsg extends Thread{
@Override
public void run() {
if(fromClient==null) return;
while(true){
try {
System.out.println("Message From Client:["+fromClient.readLine()+"]");
this.sleep(50);
} catch (IOException e) {
break;
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
public static BufferedReader fromClient=null;
public static void main(String[] args) {
try {
//get server socket
ServerSocket server=new ServerSocket(3166);
//get socket from client
Socket socket=server.accept();
System.out.println("The IP["+socket.getInetAddress()+"] is connected!");
//then we will get all the streams we need
//get information from keyboard
BufferedReader input=new BufferedReader(new InputStreamReader(System.in));
//get information from client
fromClient=new BufferedReader(new
InputStreamReader(socket.getInputStream()));
Thread th=new MyServer().new ThGetMsg();
th.start();
//get printer for client
PrintWriter toClient=new PrintWriter(socket.getOutputStream());
String inputContent="";
System.out.print("Typing Words And Press [Enter] To Send The Messge:");
inputContent=input.readLine();
while(!input.equals("termination")){
toClient.println(inputContent);
toClient.flush();
inputContent=input.readLine();
}
input.close();
toClient.close();
fromClient.close();
th.stop();
} catch (IOException e) {
e.printStackTrace();
}
}
}
二,客户端:
package com.samael.socket;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import .Socket;
import .UnknownHostException;
import com.samael.socket.MyServer.ThGetMsg;
public class MyClient {
class ThGetMsg extends Thread{
@Override
public void run() {
if(fromServer==null) return;
while(true){
try {
System.out.println("Message From Server:["+fromServer.readLine()+"]");
this.sleep(50);
} catch (IOException e) {
break;
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
public static BufferedReader fromServer=null;
public static void main(String[] args) {
try {
Socket socket=new Socket("localhost", 3166);
fromServer=new BufferedReader(new
InputStreamReader(socket.getInputStream()));
BufferedReader input=new BufferedReader(new InputStreamReader(System.in));
PrintWriter toServer=new PrintWriter(socket.getOutputStream());
Thread th=new MyClient().new ThGetMsg();
th.start();
String toServerContent="";
System.out.print("Typing Words And Press [Enter] To Send The Messge:");
toServerContent=input.readLine();
while(!toServerContent.equals("termination")){
toServer.println(toServerContent);
toServer.flush();
toServerContent=input.readLine();
}
input.close();
toServer.close();
fromServer.close();
th.stop();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
最终效果:
Server End:
How?
Message From Client:[Hey~buddy~Where am I?]
You're In My Office
Message From Client:[Really?This Is Your Office?It's So Wonderful!]
For Sure Buddy!
Client End:
Typing Words And Press [Enter] To Send The Messge:Message From Server:[How?] Hey~buddy~Where am I?
Message From Server:[You're In My Office]
Really?This Is Your Office?It's So Wonderful!
Message From Server:[For Sure Buddy!]
