Question:
If I do:
float a=5;
System.out.printf("%d", a);
Its output will be:
5.000000
How do I print 5.000000
? That is, I want to replace the comma with a period.
Answer:
Maybe this will help you:
import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;
import java.text.NumberFormat;
import java.util.Locale;
public class Teste {
public static NumberFormat seuFormato() {
DecimalFormatSymbols symbols = new DecimalFormatSymbols(Locale.ROOT);
symbols.setDecimalSeparator(',');
symbols.setGroupingSeparator('.');
return new DecimalFormat("#0.00", symbols);
}
public static void main(String[] args) {
NumberFormat formatter = seuFormato();
float a = 5;
System.out.println(formatter.format(a));
}
}
