Time Formatting

[jacklarry]

Hi,
Can you guys please tell me how you can make the time in "HH:MM" format? so that even if the user inputs the value 5 for minutes, it will output "05" instead of simply "5". Same with the hours. Thanks a lot in advance.

Well, one quick way would be to check if the minutes or hours are less than 10. If so, add a "0" in front.

Java:

if (hours < 10) {    System.out.print("0"); } System.out.print(hours + ":"); if (minutes < 10) {    System.out.print("0"); } System.out.println(minutes);

This is all assuming that hours and minutes are separate variables, of course.

why do i think there is a shorter way for this, probably just
1 or 2 lines shorter?[wonders]........[/wondering]

Yeah, I suppose using the class TheFerret is showing may be shorter.

But don't forget that my above code can be shortened to :

Java:

System.out.println((hours < 10 ? "0" : "") + hours + ":" + (minutes < 10 ? "0" : "") + minutes);

which is pretty short and doesn't require looking up methods.

dam! i just thought of it too System.out.printf();
that is what you are looking for, probably.

What about String.format? It has options for date/time formatting.
