安全
数据库
网络和加速
企业服务
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();
}
