客户端: 上传文件

public class tcp2 {

public static void main(String[]args) throws IOException
{
    System.out.println("客户端启动中");

    Socket client =new Socket("localhost",8888);

    //文件的拷贝
    InputStream is=new BufferedInputStream(new FileInputStream("src\\linux学习路线.png"));
    OutputStream os=new BufferedOutputStream(client.getOutputStream());

    byte[] data=new byte[1024*60];
    int len=-1;
    while((len=is.read(data))!=-1)
    {
        os.write(data,0,len);
    }
    os.flush();
    os.close();

    client.close();

}
}

服务器端:存储文件

public class tcp {

public static void main(String[]args) throws IOException
{
    System.out.println("服务器启动中...");
    ServerSocket server=new ServerSocket(8888);

    Socket client=server.accept();

    //文件的拷贝
    InputStream is=new BufferedInputStream(client.getInputStream());
    OutputStream os=new BufferedOutputStream(new FileOutputStream("D:/d/tu.jpg"));

    byte[] flush=new byte[1024*60];
    int len=-1;

    while((len=is.read(flush))!=-1)
    {
        os.write(flush,0,len);
    }

    is.close();
    os.close();

    client.close();

}
}
