Answer 2

My code snippet for string read/write files:

private String readTextFile(String fName) { String result = null; FileConnection fconn = null; DataInputStream is = null; try { fconn = (FileConnection) Connector.open(fName, Connector.READ_WRITE); is = fconn.openDataInputStream(); byte[] data = IOUtilities.streamToBytes(is); result = new String(data); } catch (IOException e) { System.out.println(e.getMessage()); } finally { try { if (null != is)

 is.close();
if (null != fconn)
 fconn.close();

} catch (IOException e) { System.out.println(e.getMessage()); } } return result; }

---

private void writeTextFile(String fName, String text) { DataOutputStream 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()); } 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()); } } }
