What's the fastest way to read from System.in in Java?

Question

I am reading bunch of integers separated by space or newlines from the standard in using Scanner(System.in).

Is there any faster way of doing this in Ja

Answer 1

Reading from disk, again and again, makes the Scanner slow. I like to use the combination of BufferedReader and Scanner to get the best of both worlds. i.e. speed of BufferredReader and rich and easy API of the scanner.

Scanner scanner = new Scanner(new BufferedReader(new InputStreamReader(System.in)));
