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());
}
