Guyz, please help me with my project..its all about file handling in java-J2me .I've got this problem..At first I can read the data inside the .txt in my src as my path..I have this code...

private String file() {

        InputStream is = getClass().getResourceAsStream("file.txt");
        StringBuffer sb = new StringBuffer();
        //String readline;

        try {

            int chars, i = 0;
            while ((chars = is.read()) != -1) {
                sb.append((char) chars);

            }

            return sb.toString();


        } catch (Exception e) {
        }

        return null;
    }

now, i'm having a problem in writing txt coming from the txtfield in java-j2me to .txt file.. ..

dont know how to implement with the writing so i have this code..it can determine f the .txt file exist but errors occured when i will try to run it again..

i tried to put if( fc.exist) ---}else { fc.create but it doesn't work :(..

public void writeFile() {
        try {
            OutputConnection con = (OutputConnection) Connector.open("file:///root1/myfile.txt", Connector.WRITE);

            FileConnection fc = (FileConnection)con;
            fc.create();

            OutputStream out = con.openOutputStream();
            PrintStream ps = new PrintStream(out);
            ps.println("Line1");
            ps.close();
            con.close();
            Alert alert = new Alert("Success", "Data Written successfully", null, null);
            alert.setTimeout(Alert.FOREVER);
            display.setCurrent(alert);
        } catch (ConnectionNotFoundException error) {
            System.out.println(error.getMessage());
        } catch (IOException error) {
            Alert alert = new Alert("Error", error.toString(), null, null);
            alert.setTimeout(Alert.FOREVER);
            alert.setType(AlertType.ERROR);
            display.setCurrent(alert);
        }
    }
