java控制台实现聊天程序

这篇文章主要为大家详细介绍了java控制台实现聊天程序，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了java控制台实现聊天程序的具体代码，供大家参考，具体内容如下

发送端

package ip.chat; import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.DatagramPacket; import java.net.DatagramSocket; import java.net.InetSocketAddress; public class TalkSend implements Runnable{ DatagramSocket socket = null; BufferedReader reader = null; private int formIP; private String toIP; private int toPort; public TalkSend(int formIP, String toIP, int toPort) { this.formIP = formIP; this.toIP = toIP; this.toPort = toPort; try { socket = new DatagramSocket(); reader = new BufferedReader(new InputStreamReader(system.in)); }catch (Exception e){ e.printstacktrace(); } } @Override public void run() { while (true){ try { String data = reader.readLine(); byte[] datas = data.getBytes(); DatagramPacket packet = new DatagramPacket(datas, 0, datas.length, new InetSocketAddress(this.toIP, this.toPort)); socket.send(packet); if (data.equals("bye")){ break; } }catch (Exception e){ e.printstacktrace(); } } //关闭 socket.close(); } }

服务端

package ip.chat; import java.io.IOException; import java.net.DatagramPacket; import java.net.DatagramSocket; import java.net.socketException; public class TalkReceive implements Runnable{ DatagramSocket socket = null; private int port; //设置消息来源 private String msgFrom; public TalkReceive(int port ,String msgFrom) { this.port = port; this.msgFrom = msgFrom; try { socket = new DatagramSocket(port); } catch (SocketException e) { e.printstacktrace(); } } @Override public void run() { while(true){ try { //准备接收包裹 byte[] container = new byte[1024]; DatagramPacket packet = new DatagramPacket(container,0,container.length); socket.receive(packet);//接收包裹 //断开连接 byte[] data = packet.getData(); String receiveData = new String(data, 0, data.length); System.out.println(msgFrom+"："+receiveData); if (receiveData.equals("bye")){ break; } } catch (IOException e) { e.printstacktrace(); } } socket.close(); } }

学生端代码

package ip.chat; public class TalkStudent { public static void main(String[] args) { //开启两个线程 new Thread(new TalkSend(7777,"localhost",9999)).start(); new Thread(new TalkReceive(8888,"老师")).start(); } }

教师端代码

package ip.chat; public class TalkTeacher { public static void main(String[] args) { new Thread(new TalkSend(5555,"localhost",8888)).start(); new Thread(new TalkReceive(9999,"学生")).start(); } }
