System.out.println vs PrintWriter performance comparison?

Question

I want to print 1 million lines to stdout.

System.out.println(result);

Or

PrintWriter out = new PrintWriter(System.out);
out.println(result);
out.flush();

To get better performance(speed wise), which one should I use and why?

--Edit-- How about BufferedWriter?

Answer 1

PrintWritter gives better performance, though the time difference is not quite visible in smaller programs. But becomes quite apparent as the number of lines to be printed increases.

I used the execution time of these snippets for the test. System.out.println(i)

class Sprint{
    public static void main(String[] args) {
        int n=10000000;
        for(int i=0;i<n;i++){
            System.out.println(i);
        }
    }
}

out.println(i);

import java.io.*;
class Pprint{
    public static void main(String[] args) {
        PrintWriter out = new PrintWriter(System.out);
        int n=10000000;
        for(int i=0;i<n;i++){
            out.println(i);
        }
        out.flush();
    }
}

I used n=10 to 10^7 and executed both of them 3 times for each n. There was a visible difference in performance after the value of n exceeds 10^3.
