How to format a number for String by placing points "."?

Question

I was trying to format a number by placing stitches to make it easier to read.

But with the dot it doesn’t work, but it works with commas.

Ex:

String s = String.format("%. d", 123456);

System.out.println(s);

Answer 1

The %,d is the thousand separator, and will use the default JVM location unless you specify different. To force the Brazilian location using point as separator, unlike the American using comma you can:

String.format(new Locale("pt"),"%,d",1234567)
