1. Process
(1) Can act as an input stream or dilute an output stream
(2) Supports reading from the beginning of the file , write
(3) Support reading and writing (insertion) from any location
(4) The RandomAccessFile class needs to specify the access mode:
2. Example
public void RandomAccessFile(String src, String srcMode, String dest, String destMode) { RandomAccessFile accessFile = null; RandomAccessFile accessFile1 = null; try { accessFile = new RandomAccessFile(new File(src), srcMode); accessFile = new RandomAccessFile(new File(dest), destMode); byte[] bytes = new byte[1024]; int length; while ((length = accessFile.read(bytes)) != -1) { accessFile1.write(bytes, 0, length); } } catch (IOException e) { e.printStackTrace(); } finally { if (accessFile != null) try { accessFile.close(); } catch (IOException e) { e.printStackTrace(); } if (accessFile1 != null) { try { accessFile1.close(); } catch (IOException e) { e.printStackTrace(); } } } }
