ExamLab Question - Formatting

[Richa Sharma]

Hi Guys

why does the output includes true in this examlab question?

System.out.printf("%02.2f%s%b",new Double(7),new StringBuffer("set"),"fAlSE");

Thanks
Richa

Well, try this out:

System.out.printf("%02.2f%s%b",new Double(7),new StringBuffer("set"),false);
System.out.printf("%02.2f%s%b",new Double(7),new StringBuffer("set"),"false");

Can you see the difference?

Got It Thanks Deveka

because %b will print true for any non boolean type that is not null.

[Fritz Guerilus]

I thought the answer would be:
07.00settrue
based:
on the flag being 0
and
the width being 2

But I compiled/executed the code and the answer is:
7.00settrue.

My question:
what happened to the flag & width ("%02...") portion of the format specifier?

-Thank You

The %02. portion includes the width of the fractional part too, so it says that the minimum width of the number should be 2 including the part after the decimal point...
