I'm writing an application which compares directory structure. First I wrote an application which writes gets info about files - one line about each file or directory.

My soulution is: calling method toFile

Static PrintWriter pw = new PrintWriter(new BufferedWriter( new FileWriter("DirStructure.dlis")), true);
String line; // info about file or directory
public void toFile(String line) {
    pw.println(line);
}

and of course pw.close(), at the end.

My question is, can I do it quicker? What is the quickest way?

Edit: quickest way = quickest writing in the file
