java - Fastest way to read a file line by line with 2 sets of Strings on each line?

Question

What is the fastest way I can read line by line with each line containing two Strings. An example input file would be:

Fastest, Way
To, Read
One, File
Line, By Line
.... can be a large file

There are always two sets of strings on each line that I need even if there are spaces between the String e.g. "By Line"

Currently I am using

FileReader a = new FileReader(file);
            BufferedReader br = new BufferedReader(a);
            String line;
            line = br.readLine();

            long b = System.currentTimeMillis();
            while(line != null){

Is that efficient enough or is there a more efficient way using standard JAVA API (no outside libraries please) Any help is appreciated Thanks!

Answer 1

It depends what do you mean when you say "efficient." From the point of view of performance it is OK. If you are asking about the code style and size, I pesonally do almost you do with a small correction:

        BufferedReader br = new BufferedReader(new FileReader(file));
        String line;
        while((line = br.readLine()) != null) {
             // do something with line.
        }

For reading from STDIN Java 6 offers you yet another way. Use class Console and its methods

readLine() and readLine(fmt, Object... args)
