System.out.printf does not print formats in netbeans 11.2(java)

Question

I tried to print integers by using this format: int x=7 --> output = 07 so I have write this code:

public class test{
public static void main(String[] args){
int x=7;
System.out.printf("your converted number = %02d",x);
}
}

but the OUTPUT in Netbeans 11.2 IDE is :

your converted number = ??

how can I fix this error in my own Netbeans version?

That's very unexpected. Is that copy-and-pasted code, or did you re-type it? — Daniel, May 12 '20 at 17:37

No worries. I'm asking because I want to make sure we're looking at the *exact* code that is causing the problem. Please use copy and paste, both for the code and for the output. For the record, when I run the code in your quest, I get the output `your converted number = 07`. — Daniel, May 12 '20 at 17:43
Yes...If you copy this code in your Netbeans 11.2 IDE you will see the same output — Nameless, May 12 '20 at 17:46

I think it may have to do with internationalization setting for your locale. See: String.format prints 'question mark' as output

Still not worked in my IDE ...can you please download netbeans 11.2 and test my code ?Maybe after that you can give me more clear answere – Nameless May 12 '20 at 19:33
I am not even going to try because I know the results depend on your/my computer's operating system country and language (locale) settings that conflict on your setup but will work fine for countries using Latin alphabet and English codepage settings, see: https://www.oracle.com/java/technologies/javase/jdk8-jre8-suported-locales.html – JohannesB May 12 '20 at 19:52
