如题，将String保存成文件。 /** * 将String数据存为文件 */ public static File getFileFromBytes(String name,String path) { byte[] b=name.getBytes(); BufferedOutputStream stream = null; File file = null; try { file = new File(path); FileOutputStream fstream = new FileOutputStream(file); stream = new BufferedOutputStream(fstream); stream.write(b); } catch (Exception e) { e.printStackTrace(); } finally { if (stream != null) { try { stream.close(); } catch (IOException e1) { e1.printStackTrace(); } } } return file; }

byte数据保存为文件：

/** * 将byte数据存为文件 */ public static File getFileFromBytes(byte[] b,String path) { BufferedOutputStream stream = null; File file = null; try { file = new File(path); FileOutputStream fstream = new FileOutputStream(file); stream = new BufferedOutputStream(fstream); stream.write(b); } catch (Exception e) { e.printStackTrace(); } finally { if (stream != null) { try { stream.close(); } catch (IOException e1) { e1.printStackTrace(); } } } return file; }
