JavaIP小练习

一、客户端

package Ip;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.InetAddress;
import java.net.Socket;


public class iptest {

    public static void main(String[] args) throws IOException {
        // InetAddress ip=InetAddress.getLocalHost();
        try {
            System.out.println("机号:" + InetAddress.getLocalHost().getHostName());
            System.out.println("ip地址为："+ InetAddress.getLocalHost().getHostAddress());

            Socket socket = new Socket("192.168.16.10", 8880);//此类实现客户端套接字（也可以就叫“套接字”）。套接字是两台机器间通信的端点。 
            OutputStream os = socket.getOutputStream();//返回此套接字的输出流。
            PrintStream ps = new PrintStream(os);//PrintStream 为其他输出流添加了功能，使它们能够方便地打印各种数据值表示形式
            String info = "我是本机1";
            ps.write(info.getBytes());
            socket.shutdownOutput();//禁用此套接字的输出流。
            InputStream is = socket.getInputStream();//返回此套接字的输入流。
            BufferedReader br = new BufferedReader(new InputStreamReader(is));
            String infop;
            while ((infop = br.readLine()) != null) {
                System.out.println(infop);
            }
            ps.close();
            os.close();
            socket.close();
            System.out.println("发送完毕");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

二、服务端

package Ip;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;

public class tet {
    public static void main(String[] args) {
        try {
            ServerSocket server = new ServerSocket(8880);//此类实现服务器套接字
            while (true) {
                Socket socket = server.accept();//侦听并接受到此套接字的连接(必须要)。
                InputStream is = socket.getInputStream();//返回此套接字的输入流。
                BufferedReader br = new BufferedReader(new InputStreamReader(is));
                String info;
                while ((info = br.readLine()) != null) {
                    System.out.println(info);
                }
                socket.shutdownInput();// 此套接字的输入流置于“流的末尾”。
                OutputStream os = socket.getOutputStream();//返回此套接字的输出流。
                PrintStream ps = new PrintStream(os);//PrintStream 为其他输出流添加了功能，使它们能够方便地打印各种数据值表示形式
                String reStr = "别刷屏";
                ps.write(reStr.getBytes());
                ps.close();
                os.close();
                is.close();
                server.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}
