socket 插座,**套接字**,插口

**readLine**

是BufferedReader对象提供的方法

newLine  
是BufferedWriter对象提供的方法

**服务器：**

package one;  
  
import java.io.BufferedReader;  
import java.io.IOException;  
import java.io.InputStreamReader;  
import java.io.OutputStreamWriter;  
import java.net.ServerSocket;  
import java.net.Socket;  
  
public class ServerTest \{  
  
  
public static void main(String\[\] args) \{  
try \{  
ServerSocket serverSocket = new ServerSocket(8888);  
Socket socket = serverSocket.accept();//判断客户端是否连接上服务器，连接上通过Socket进行相互通信  
ServerThread th = new ServerThread(socket);  
th.start();//开启线程  
/\*定义一个邮递员serverSocket,然后邮递员serverSocket把接收到的“东西放进socket袋子中”，  
之后开启线程，可以socket.输出流，随后用OutputStreamWriter把字节形式的流转换成  
字符流（桥梁的作用），写入文字和字符等 new OutputStreamWriter(socket.getOutputStream())\*/  
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));  
while(true)\{  
String message = br.readLine();  
System.out.println("读取客户端："+message);  
\}  
\} catch (IOException e) \{  
// TODO Auto-generated catch block  
e.printStackTrace();  
\}  
\}  
  
  
\}

**服务器线程：**

package one;  
  
  
import java.io.BufferedWriter;  
import java.io.IOException;  
import java.io.OutputStreamWriter;  
import java.net.Socket;  
import java.util.Scanner;  
  
  
public class ServerThread extends Thread\{  
private Socket socket;  
  
public ServerThread(Socket socket) \{  
super();  
this.socket = socket;  
\}  
  
  
@Override  
public void run() \{  
Scanner sc = new Scanner(System.in);  
try \{  
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));  
while(true)\{  
String str = sc.nextLine();  
bw.write(str);  
bw.newLine();  
bw.flush();  
\}  
\} catch (IOException e) \{  
// TODO Auto-generated catch block  
e.printStackTrace();  
\}  
\}  
  
  
\}

**客户端：**

package one;  
  
import java.io.BufferedReader;  
import java.io.IOException;  
import java.io.InputStreamReader;  
import java.net.Socket;  
import java.net.UnknownHostException;  
  
public class ClientTest \{  
public static void main(String\[\] args) \{  
try \{  
/\*获取本地服务器127.0.0.1，端口号为8888.把接收到的“东西放进socket袋子中”，  
之后开启线程，可以socket.输出流，随后用OutputStreamWriter把字节形式的流转换成  
字符流（桥梁的作用），写入文字和字符等 new OutputStreamWriter(socket.getOutputStream())\*/  
  
Socket socket = new Socket("127.0.0.1", 8888);  
ClientThread th = new ClientThread(socket);  
th.start();  
  
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));  
while(true)\{  
String message = br.readLine();  
System.out.println("读取服务器端："+message);  
\}  
\} catch (UnknownHostException e) \{  
// TODO Auto-generated catch block  
e.printStackTrace();  
\} catch (IOException e) \{  
// TODO Auto-generated catch block  
e.printStackTrace();  
\}  
\}  
\}
