  //读取网站图片
//1.先复制网站图片的地址
URL url = new URL("https://www.baidu.com/img/bd_logo1.png");
//2.打开连接
  URLConnection openConnection = url.openConnection();   
  openConnection.connect();
 
  //3.获取流
  InputStream in = openConnection.getInputStream();
 
 
  FileOutputStream fout = new FileOutputStream("D:/233.png");
  BufferedOutputStream bout = new BufferedOutputStream(fout);
  //按字节读写!!!
  int data  = in.read() ;
while(data!=-1){
bout.write(data); //上面已经读了一次,所以现在应该先写
data = in.read();
 
}
// byte []b = new byte[1024];
// int len = -1;
// while((len=in.read(b))!=-1){
// bout.write(b,0,len);
// }
