java socket编程
server端：
1 import java.io.BufferedReader; 2 import java.io.IOException; 3 import java.io.InputStream; 4 import java.io.InputStreamReader; 5 import java.io.OutputStream; 6 import java.net.ServerSocket; 7 import java.net.Socket; 8 9 10 public class ServerSocketTest { 11 12 13 public static void main(String[] args) { 14 try { 15 ServerSocket ss=new ServerSocket(1235); 16 System.out.print("server"); 17 Socket socket=ss.accept(); 18 19 InputStream is=socket.getInputStream(); 20 BufferedReader br = new BufferedReader(new InputStreamReader(is)); 21 String info=null; 22 if((info=br.readLine())!=null){ 23 System.out.print(info); 24 } 25 26 OutputStream os=socket.getOutputStream(); 27 String s="hello"; 28 os.write(s.getBytes()); 29 30 os.close(); 31 br.close(); 32 is.close(); 33 socket.close(); 34 ss.close(); 35 36 } catch (IOException e) { 37 e.printStackTrace(); 38 } 39 40 } 41 42 }
client端：
1 import java.io.BufferedReader; 2 import java.io.IOException; 3 import java.io.InputStream; 4 import java.io.InputStreamReader; 5 import java.io.OutputStream; 6 import java.net.Socket; 7 import java.net.UnknownHostException; 8 9 10 public class SocketTest { 11 12 13 public static void main(String[] args) { 14 try { 15 Socket socket=new Socket("localhost", 1235); 16 System.out.println("client"); 17 OutputStream os=socket.getOutputStream(); 18 String s="123"; 19 os.write(s.getBytes()); 20 socket.shutdownOutput(); 21 22 InputStream is=socket.getInputStream(); 23 BufferedReader br = new BufferedReader(new InputStreamReader(is)); 24 String info=null; 25 if((info=br.readLine())!=null){ 26 System.out.print(info); 27 } 28 29 br.close(); 30 is.close(); 31 os.close(); 32 socket.close(); 33 34 } catch (UnknownHostException e) { 35 e.printStackTrace(); 36 } catch (IOException e) { 37 e.printStackTrace(); 38 } 39 40 } 41 42 }
