java本地客户端与服务器连接并相互发送数据

 分享一下我写的代码，自豪地分享，完全原创。

以下为服务器端的代码:

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.PrintStream;

import java.net.ServerSocket;

import java.net.Socket;

import java.net.InetAddress;

import java.net.InetSocketAddress;



public class Server {

	public static void main(String[] args) {

		CreateServer cs = new CreateServer() ;

		SReserive sr = new SReserive(cs.getSocket()) ;

		sr.start() ;

		ServerSend ss = new ServerSend(cs.getSocket()) ;

		ss.start() ;

	}

}



class CreateServer {

	private ServerSocket server = null ;

	private Socket socket = null ;



	public CreateServer() {

		try {

			server = new ServerSocket(5000) ;

			socket = server.accept() ;

		}catch (IOException e) {

			e.printStackTrace();

		}catch (Exception e) {

			e.printStackTrace();

		}

	}



	public ServerSocket getServer() {

		return server;

	}



	public void setServer(ServerSocket server) {

		this.server = server;

	}



	public Socket getSocket() {

		return socket;

	}



	public void setSocket(Socket socket) {

		this.socket = socket;

	}

}



class SReserive extends Thread {

	private Socket socket ;

	private BufferedReader br ;



	public SReserive(Socket socket) {

		this.socket = socket ;

		try {

			br = new BufferedReader(new InputStreamReader(this.socket.getInputStream())) ;

		}catch (IOException e) {

			e.printStackTrace();

		}

	}



	public void run() {

		try {

			String line ;

			line = br.readLine() ;

			while(!line.equals("bye")) {

				System.out.println("Client: " + line) ;

				line = br.readLine() ;

			}

		}catch(IOException e) {

			e.printStackTrace() ;

		}

	}



}



class ServerSend extends Thread {

	private BufferedReader br = new BufferedReader(new InputStreamReader(System.in)) ;

	private PrintStream ps ;



	public ServerSend(Socket socket) {

		try {

			ps = new PrintStream(socket.getOutputStream()) ;

		} catch (IOException e) {

			e.printStackTrace();

		}

	}



	public void run() {

		String line ;

		try {

			line = br.readLine() ;

			while(!line.equals("bye")) {

				ps.println(line) ;

				ps.flush() ;

				line = br.readLine() ;

			}

		} catch (IOException e) {

			e.printStackTrace();

		} catch (Exception e) {

			e.printStackTrace();

		}



	}

}



class Close {

	public Close(Socket socket, ServerSocket server) {

		try {

			socket.close() ;

			server.close() ;

		}catch (IOException e) {

			e.printStackTrace();

		}catch (Exception e) {

			e.printStackTrace();

		}

	}

}

一下是客户端代码：

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.PrintStream;

import java.net.InetAddress;

import java.net.Socket;

import java.net.UnknownHostException;



public class Client {

	public static void main(String[] args) {

		CreateConnection cc = new CreateConnection() ;

		Sending sd = new Sending(cc.getSocket()) ;

		sd.start() ;

		CReserive cr = new CReserive(cc.getSocket()) ;

		cr.start() ;

	}

}



class CreateConnection {

	private Socket socket ;

	private InetAddress ia ;



	public CreateConnection() {

		try {

			ia = InetAddress.getByAddress(new byte[]{(byte)127,(byte)0,(byte)1,(byte)1}) ;

			socket = new Socket(ia, 5000) ;

		} catch (UnknownHostException e) {

			e.printStackTrace();

		} catch (IOException e) {

			e.printStackTrace();

		}

	}



	public Socket getSocket() {

		return socket;

	}



	public void setSocket(Socket socket) {

		this.socket = socket;

	}



}



class Sending extends Thread {

	private Socket socket ;

	private BufferedReader br ;

	private PrintStream ps ;



	public Sending(Socket socket) {

		this.socket = socket ;

		br = new BufferedReader(new InputStreamReader(System.in)) ;

		try {

			ps = new PrintStream(this.socket.getOutputStream()) ;

		} catch (IOException e) {

			e.printStackTrace();

		}

	}



	public void run() {

		String line ;

		try {

			line = br.readLine() ;

			while(!line.equals("bye")) {

				ps.println(line) ;

				ps.flush() ;

				line = br.readLine() ;

			}

		} catch (IOException e) {

			e.printStackTrace();

		}

	}



}



class CReserive extends Thread {

	private Socket socket ;

	private BufferedReader br ;



	public CReserive(Socket socket) {

		this.socket = socket ;

		try {

			br = new BufferedReader(new InputStreamReader(this.socket.getInputStream())) ;

		}catch (IOException e) {

			e.printStackTrace();

		}

	}



	public void run() {

		try {

			String line ;

			line = br.readLine() ;

			while(!line.equals("bye")) {

				System.out.println("Server: " + line) ;

				line = br.readLine() ;

			}

		}catch(IOException e) {

			e.printStackTrace() ;

		}

	}



}

解析一下两端代码的功能，服务器端和客户端同为多线程实现，同为两个线程，一个接受数据并打印，一个发送数据，读者可以自己理解下，不明白的可以给我留言！
