java简易聊天室

你要的就是点对点通信，见以下例子：

1.简单服务器端

/*

import java.net.*;

import java.io.*;

*/

ServerSocket server=null;

try {

server=new ServerSocket(%%1);

}catch(Exception e){

System.out.println("不能监听:"+e.toString());

}

Socket socket=null;

try {

socket=server.accept();

BufferedReader %%3=new BufferedReader(new InputStreamReader(socket.getInputStream()));

PrintWriter %%4=new PrintWriter(socket.getOutputStream());

String %%2=%%3.readLine();

%%4.println("");

%%4.flush();

%%4.close();

%%3.close();

}

catch(IOException e){

System.out.println("出错:"+e.toString());

}finally{

try {

if(socket!=null){

socket.close();

server.close();

}

}

catch(IOException e){

e.printStackTrace();

}

}

2.简单客户端

/*

import java.net.*;

import java.io.*;

*/

Socket socket=null;

try {

socket=new Socket(%%1,%%2);

PrintWriter %%3=new PrintWriter(socket.getOutputStream());

BufferedReader %%4 = new BufferedReader(new InputStreamReader(socket.getInputStream()));

%%3.println("");

%%3.flush();

String %%5=%%4.readLine();

%%6

%%3.close();

%%4.close();

}catch(Exception e){

e.printStackTrace();

}

finally{

try {

socket.close();

}

catch(IOException e){

e.printStackTrace();

}

}

3.获得本机IP

//import java.net.*;

String strIP = null;

try

{

strIP =InetAddress.getLocalHost().getHostAddress().toString();

}

catch(UnknownHostException e)

{

e.printStackTrace();

}

/*

%%1=InetAddress.getLocalHost().getHostAddress();

EnumerationNetworkInterface netInterfaces = null;

try {

netInterfaces = NetworkInterface.getNetworkInterfaces();

while (netInterfaces.hasMoreElements()) {

NetworkInterface ni = netInterfaces.nextElement();

System.out.println("DisplayName:" + ni.getDisplayName());

System.out.println("Name:" + ni.getName());

EnumerationInetAddress ips = ni.getInetAddresses();

while (ips.hasMoreElements()) {

System.out.println("IP:"

+ ips.nextElement().getHostAddress());

}

}

} catch (Exception e) {

e.printStackTrace();

}

*/

5.点对点通信

/*

import java.io.*;

import java.net.*;

*/

public class %%6 extends Thread {

@Override

public void run() {

ServerSocket server = null;

try {

server = new ServerSocket(5000);

} catch (Exception e) {

System.out.println("不能监听:" + e.toString());

}

Socket socket = null;

try {

socket = server.accept();

BufferedReader req = new BufferedReader(new InputStreamReader(

socket.getInputStream()));

PrintWriter os = new PrintWriter(socket.getOutputStream());

Debug.p(req.readLine());

os.println("Server");

os.flush();

os.close();

req.close();

} catch (IOException e) {

System.out.println("出错:" + e.toString());

} finally {

try {

if (socket != null) {

socket.close();

server.close();

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

Thread t = new %%6();

t.start();

String strIP = null;

try {

strIP = InetAddress.getLocalHost().getHostAddress().toString();

} catch (UnknownHostException e) {

e.printStackTrace();

}

Socket socket = null;

try {

socket = new Socket(strIP, 4000);

PrintWriter pw = new PrintWriter(socket.getOutputStream());

BufferedReader br = new BufferedReader(new InputStreamReader(socket

.getInputStream()));

pw.println("Client");

pw.flush();

Debug.p(br.readLine());

pw.close();

br.close();

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

socket.close();

} catch (IOException e) {

e.printStackTrace();

}

}
