Efficieny of this TextFile reader class?

Question

I'm trying to make a class especially for handling text files.
how efficient is this class?
code:
final class TextReader {
     public static ArrayList readTextFile(String fileName) {
          ArrayList result = new ArrayList();
          String tempstr;
          try {
               FileReader fReader = new FileReader(fileName);
               BufferedReader bReader = new BufferedReader(fReader);
               while ((tempstr = bReader.readLine()) != null) {
                    result.add(tempstr);
fReader.close();
     } catch (Exception err) {
               err.printStackTrace();
     return result;
}

Sorry if my question is unclear.
But if you would look at my above implementation, I use static in my method.
So I would call:
ArrayList list = TextReader.readTextFile(textfile);
Or is it better that I leave the static out:
Init(){
TextReader tReader = new TextReader();//empty TextReader constructor
//.......somewhere below
ArrayList list = tReader.readTextFile(textfile);
What I generally want to know is there a better way of implementating a TextReader class than what I did(1 that put a string in an arraylist)?
thx for the replies.
