public String readFile(String path) { InputStream is = null; FileConnection fc = null; String str = ""; try { fc = (FileConnection)Connector.open(path, Connector.READ_WRITE); if(fc.exists()) { int size = (int)fc.fileSize(); is= fc.openInputStream(); byte bytes[] = new byte[size]; is.read(bytes, 0, size); str = new String(bytes, 0, size); } } catch (IOException ioe) { Alert error = new Alert("Error", ioe.getMessage(), null, AlertType.INFO); error.setTimeout(1212313123); Display.getDisplay(main).setCurrent(error);} finally { try { if (null != is) is.close(); if (null != fc) fc.close(); } catch (IOException e) { System.out.println(e.getMessage()); } } return str; } void writeTextFile(String fName, String text) { OutputStream os = null; FileConnection fconn = null; try { fconn = (FileConnection) Connector.open(fName, Connector.READ_WRITE); if (!fconn.exists()) fconn.create(); os = fconn.openDataOutputStream(); os.write(text.getBytes()); fconn.setHidden(false); // fconn.setReadable(true); } catch (IOException e) { System.out.println(e.getMessage()); } finally { try { if (null != os) os.close(); if (null != fconn) fconn.close(); } catch (IOException e) { System.out.println(e.getMessage()); } } }
