客户端代码

import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class Client {

	public static void main(String[] args) throws IOException {
		//先建立端口
		Socket socket = new Socket(InetAddress.getLocalHost(),20000);
		//建立工作者
		Woker woker = new Woker(socket);
		//向服务器发送数据的线程
		new Thread(new Sender(woker)).start();
		//接受服务器数据的线程
		new Thread(new Receiver(woker)).start();
	}
}

服务端代码

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {

	public static void main(String[] args) throws IOException {
		ServerSocket socket1 = new ServerSocket(20000);
		Socket socket = socket1.accept();
		//工作者
		Woker woker = new Woker(socket);
		//向客户端发送数据线程
		new Thread(new Sender(woker)).start();
		//接受客户端数据线程
		new Thread(new Receiver(woker)).start();
	}

}

工作类（将数据的发送与接收面向对象）

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;

public class Woker {
	Socket socket;
	BufferedReader buf ;
	BufferedWriter buw ;
	BufferedReader in ;
	public Woker(Socket socket) throws IOException {
		this.socket = socket;
		buf = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		buw = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
		in = new BufferedReader(new InputStreamReader(System.in));
	}
	public void send() throws IOException {
		 
		while(true) {
			
			buw.write(in.readLine());
			buw.newLine();
			buw.flush();
		}
	}
	public void receive() throws IOException {
		while(true) {
			System.out.println(buf.readLine());
		}
	}
}

发送线程

import java.io.IOException;

public class Sender implements Runnable{
	Woker woker ;
	public Sender(Woker woker) {
		this.woker = woker;
	}
	@Override
	public void run() {
		try {
			woker.send();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

接收线程 

import java.io.IOException;

public class Receiver implements Runnable{
	Woker woker ;
	public Receiver(Woker woker) {
		this.woker = woker;
	}
	@Override
	public void run() {
		// TODO Auto-generated method stub
		try {
			woker.receive();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
}
