Efficiency while reading a txt file to an array

I have written a script in which I read in .txt files to arrays. It works perfectly but I'm curious if there is a more efficient way of reading the .txt files in. I have this:

try {
    String line;
    filestart = new BufferedReader(new FileReader("C:\\path\\file.txt));
    for (line = filestart.readLine(); line !=null; line = filestart.readLine()) {
        array.add (line);  
    }
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

Is there a function that combines BufferedReader and FileReader?

How would Scanner compare with what I have?

[see this post](http://stackoverflow.com/questions/2231369/scanner-vs-bufferedreader) on the subject. – Eliran Malka Jul 25 '12 at 10:58
Thanks. That's useful to know. – Jul 25 '12 at 11:02

Seems efficient enough. For less code, look at Google Guava's `Files#readLines`. – maksimov Jul 25 '12 at 11:05

In java 7 java.nio.files.Files#readAllLines, but actually does the same thing as you already do – Kennet Jul 25 '12 at 13:22

And I just now realized my use of "a" instead of "of." Whoops. – jrad Jul 25 '12 at 16:13

Whilst that is true, I can't see where anyone used it. Except here. – Jul 25 '12 at 16:14

@SeanKenny - It is in the question's title: "Efficiency whilst reading a txt file to an array" – Jesse Webb Jul 25 '12 at 19:10

Sorry, yeah. Don't even know the title to my own question. Great work. – Jul 26 '12 at 09:02
