## 實例 ~~~ File current = new File("/Users/jiee/Desktop/Java/Test/source"); //目標文件夾 File distFileD = new File("/Users/jiee/Desktop/Java/Test/dist"); if (!distFileD.exists()) { distFileD.mkdir(); } File[] files = current.listFiles(); for (File file : files) { File distFile = new File(distFileD, file.getName()); BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream(file)); BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(new FileOutputStream(distFile)); int len = 0; byte[] bs = new byte[1024]; while ((len = bufferedInputStream.read(bs)) != -1) { bufferedOutputStream.write(bs, 0, len); } bufferedOutputStream.close(); bufferedInputStream.close(); } ~~~
