Hello,
I'm creating a method which formats big numbers. I want a decimal separator.
For example: How can i change 14000000 into 14,000,000?
I'm using NumberFormat and or DecimalFormat.
I currently have this code: (I know its tiny)

	String numberFormat(final int number) {

		DecimalFormat formatter = new DecimalFormat("#.##");

		return (formatter.format(number));

	}

To avoid any hacks as a string, you can simply print it in a UK locale with right decimal separator (JDK 1.5+)

System.out.printf(Locale.UK, "%6.2f%n", 123456.78);

A more complete example using locales:

import java.text.NumberFormat;
import java.util.Locale;

class DecimalFormat1 {
    public static void main(String args[]) {
        NumberFormat nf2 =
        NumberFormat.getInstance(Locale.UK);
        System.out.println(nf2.format(1234.56));
    }
}
