String.format("%08d", myInt) will return a string 0 padded to a width of 8. But is there a way to have the amount of padding determined from a variable instead of having ot hardcode 8 in there? So if my program determines the padding needs to be X it can just use X in the String.format() method somehow?
I didn't see it in the API, but I may have overlooked it. I'm using Java 1.5
Thanks

Like so...?
public class FormatTest {public static void main( String [] args ) {
int myInt = 2473;
int eight = 8;
System.out.println( String.format("%0"+ eight + "d", myInt) ); // Prints 00002473
}
}

What about this:
import java.util.Formatter ;public class FormatTest {
public static void main( String [] args ) {
int myInt = 2473;
int eight = 8;
String format = new Formatter().format("%%0%dd%%n", eight).toString();
System.out.format(format, myInt); // Prints 00002473
}
}
:-))
