本文實例講述了java實現從網上下載圖片到本地的方法。分享給大家供大家參考。具體如下：
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(); }}希望本文所述對大家的java程序設計有所幫助。
