    public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
//照片URL
        String imageUrl = "https://www.baidu.com/img/bd_logo1.png";
        URL url = new URL(imageUrl);
//打开网络输入流
        DataInputStream dis = new DataInputStream(url.openStream());
        String newImageName="E://image/1.jpg";
//建立一个新的文件
        FileOutputStream fos = new FileOutputStream(new File(newImageName));
        byte[] buffer = new byte[1024];
        int length;
//开始填充数据
        while((length = dis.read(buffer))>0){
            fos.write(buffer,0,length);
        }
        dis.close();
        fos.close();
    }
