這篇文章主要為大家詳細(xì)介紹了java控制臺(tái)實(shí)現(xiàn)聊天程序，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了java控制臺(tái)實(shí)現(xiàn)聊天程序的具體代碼，供大家參考，具體內(nèi)容如下

發(fā)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();
            }
        }

        //關(guān)閉
        socket.close();
    }
}

服務(wù)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;
    //設(shè)置消息來(lái)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 {
                //準(zhǔn)備接收包裹
                byte[] container = new byte[1024];

                DatagramPacket packet = new DatagramPacket(container,0,container.length);
                socket.receive(packet);//接收包裹

                //斷開(kāi)連接
                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();
    }
}

學(xué)生端代碼

package ip.chat;

public class TalkStudent {
    public static void main(String[] args) {
        //開(kāi)啟兩個(gè)線(xiàn)程
        new Thread(new TalkSend(7777,"localhost",9999)).start();
        new Thread(new TalkReceive(8888,"老師")).start();
        
    }
}

教師端代碼

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,"學(xué)生")).start();
 
  }
}
