本文实例讲述了java实现从网上下载图片到本地的方法。分享给大家供大家参考。具体如下：
import java.io.*; import java.net.MalformedURLException; import java.net.URL; public static void writeFile(String strUrl,String fileName){ URL url = null; try { url = new URL(strUrl); } catch (MalformedURLException e2) { e2.printStackTrace(); } InputStream is = null; try { is = url.openStream(); } catch (IOException e1) { e1.printStackTrace(); } OutputStream os = null; File f = new File("d:webimg"); f.mkdirs(); try{ os = new FileOutputStream("d:webimg"+fileName); int bytesRead = 0; byte[] buffer = new byte[8192]; while((bytesRead = is.read(buffer,0,8192))!=-1){ os.write(buffer,0,bytesRead); } }catch(FileNotFoundException e){ } catch (IOException e) { e.printStackTrace(); } }
希望本文所述对大家的java程序设计有所帮助。
