客户端

复制代码 代码如下:

import java.io.bufferedreader;
import java.io.inputstreamreader;
import java.io.printwriter;
import java.net.socket;

public class myclient { 
    public static void main(string[] args) throws exception { 
        socket socket = new socket("localhost", 10000); 
        bufferedreader in = new bufferedreader(new inputstreamreader(socket.getinputstream())); 
        printwriter out = new printwriter(socket.getoutputstream()); 
        bufferedreader reader = new bufferedreader(new inputstreamreader(system.in)); 

        while (true) { 
            string msg = reader.readline(); 
            out.println(msg); 
            out.flush(); 
            if (msg.equals("bye")) { 
                break; 
            } 
            system.out.println(in.readline()); 
        } 
        socket.close(); 
    } 
} 

服务端

复制代码 代码如下:

import java.io.bufferedreader;
import java.io.ioexception;
import java.io.inputstreamreader;
import java.io.printwriter;
import java.net.serversocket;
import java.net.socket;

public class myserver { 
    public static void main(string[] args) throws ioexception { 
        serversocket server = new serversocket(10000); 

        while (true) { 
            socket socket = server.accept(); 
            invoke(socket); 
        } 
    } 

    private static void invoke(final socket client) throws ioexception { 
        new thread(new runnable() { 
            public void run() { 
                bufferedreader in = null; 
                printwriter out = null; 
                try { 
                    in = new bufferedreader(new inputstreamreader(client.getinputstream())); 
                    out = new printwriter(client.getoutputstream()); 

                    while (true) { 
                        string msg = in.readline(); 
                        system.out.println(msg); 
                        out.println("server received " + msg); 
                        out.flush(); 
                        if (msg.equals("bye")) { 
                            break; 
                        } 
                    } 
                } catch(ioexception ex) { 
                    ex.printstacktrace(); 
                } finally { 
                    try { 
                        in.close(); 
                    } catch (exception e) {} 
                    try { 
                        out.close(); 
                    } catch (exception e) {} 
                    try { 
                        client.close(); 
                    } catch (exception e) {} 
                } 
            } 
        }).start(); 
    } 
}
