服务端

package wanfeng;

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;

public class TCPserver1 {
    public static void main(String[] args) throws IOException {
        // 创建服务器Socket对象
        ServerSocket ss = new ServerSocket(9000);

        // 监听客户端连接
        Socket s = ss.accept();
       
       InputStream inputStream=s.getInputStream();
       //接受到的文件输送到目标文件夹
       OutputStream outputStream=new FileOutputStream("D:\\hello\\H1.JPG");

       byte[] buffer=new byte[1024];
       int len=0;
       while((len=inputStream.read(buffer))!=-1)
       {
           outputStream.write(buffer,0,len);
       }

        outputStream.close();
       inputStream.close();
        s.close();
    }
}

客户端

package wanfeng;

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
import java.net.SocketAddress;
import java.util.Random;

public class TCPclient1 {
    public static void main(String[] args) throws IOException {
        // 创建客户端Socket对象
        Socket socket = new Socket("127.0.0.1",9000);
        OutputStream outputStream=socket.getOutputStream();
        InputStream inputStream=new FileInputStream("D:\\360downloads\\222.JPG");//输入流读取图片

        byte[] buffer=new byte[1024];
        int len=0;
        while((len=inputStream.read(buffer))!=-1)
        {
         outputStream.write(buffer,0,len);//向服务端输送
        }
        outputStream.close();
        inputStream.close();
        socket.close();
    }
