For writing text files ==========================================================================


    outputFile = null;


Create the file:

    File filePathInfo = new File(path, fileName);
    FileOutputStream outputFile = new FileOutputStream(filePathInfo, APPEND);

Write the file:

    public int writeText(String txt)
    {
       int i;
       char[] ch = txt.toCharArray();   // Treat as ints for Unicode

       try
       {
            for (i = 0; i < txt.length(); i++)
            {
                outputFile.write( (int) ch[i]);		// Write the data
            }
            outputFile.close();				// Close the file

        } catch (FileNotFoundException ex)  // Things might go wrong
        {
            return 0;
        }catch (IOException e)
        {
            return 0;
        }
        return 1;                        
    }
  

To read the data================================================================================

	FileReader readFile;
	BufferedReader buffreader;


Open the file:


    public int OpenTextFile(String fileName)
    {
       File inputFileName = new File(fileName);
       int readFlag = 0;

       try
       {    // Try to get an input file stream
           readFile = new FileReader(inputFileName);
           buffreader = new BufferedReader(readFile);
           
        } catch (FileNotFoundException ex) {
            return 1;
        }
        return 0;
    }


Read from the file:

    public String ReadOneLine()
    {
        String text;
        
        try
        {         
            text = buffreader.readLine();
        } catch (IOException ex) {
            return null;
        }
       return text; 
    }

Close the file:

    public void CloseRead()
    {
        try
        {
            buffreader.close();
        } catch (IOException ex) {
            System.exit(0);
        }
        
    }
