网络编程练习：聊天

【需求】：实现双方聊天（收数据和发数据）

【技术】：网络编程、IO流、多线程

【代码】：

 /* 需求：实现双方聊天（收数据和发数据） 所需技术：网络编程、IO流、多线程 */ import java.net.*; import java.io.*; class SendInfo implements Runnable { 	private DatagramSocket ds; 	public SendInfo(DatagramSocket ds){ 		this.ds=ds; 	} 	public void run(){ 		try{ 			BufferedReader bufr=new BufferedReader(new InputStreamReader(System.in)); 			String line=null; 			while((line=bufr.readLine())!=null){ 				if("0000".equals(line)) 					break; 				byte[] buf=line.getBytes(); 				DatagramPacket dp=new DatagramPacket(buf,buf.length,InetAddress.getByName("127.0.0.1"),10001); 				ds.send(dp); 			} 		} 		catch (Exception e){ 			throw new RuntimeException("发送数据异常！！！"); 		} 	} } class ReceInfo implements Runnable { 	private DatagramSocket ds; 	public ReceInfo(DatagramSocket ds){ 		this.ds=ds; 	} 	public void run(){ 		try{ 			while(true){ 				byte[] buf=new byte[1024]; 				DatagramPacket dp=new DatagramPacket(buf,buf.length); 				ds.receive(dp); 				String ip=dp.getAddress().getHostAddress(); 				String data=new String(dp.getData(),0,dp.getLength()); 				int port=dp.getPort(); 				System.out.println(ip+"\\"+port+"::"+data); 			} 		} 		catch (Exception e){ 			throw new RuntimeException("接收数据异常！！！"); 		} 	} } class UdpChat { 	public static void main(String[] args) throws Exception 	{ 		DatagramSocket sendSocket=new DatagramSocket(6666); 		DatagramSocket receSocket=new DatagramSocket(10001); 		 		new Thread(new SendInfo(sendSocket)).start(); 		new Thread(new ReceInfo(receSocket)).start(); 	} }
