    You can use fileWriter with a true for appending.

    try
    {
        String filename= "MyFile.txt";
        FileWriter fw = new FileWriter(filename,true); //the true will append the new data
        fw.write("add a line\n");//appends the string to the file
        fw.close();
    }
    catch(IOException ioe)
    {
        System.err.println("IOException: " + ioe.getMessage());
    }
