Format issue

[jomypgeorge]

hi friends,
i have an issue in formatting. i tried to pad zeros and add minus sign but it produce exception. but if i add plus sin then it works fine.

class FormatTest1
{
public static void main(String ... args)
{
int i2 = 123456;
System.out.format(">%2$+,09d< \n", i2,100000);
}
}

it works ok
but
class FormatTest1
{
public static void main(String ... args)
{
int i2 = 123456;
System.out.format(">%2$-,09d< \n", i2,100000);
}
}
get exception

whats happening here?

It has nothing to do with negative numbers, you're asking the formatter to left justify a number and pad it with zeros (on the left). It can't do that. Either leave out the minus sign or the zero.

kind regards,

thanks JosAH

i thought "-" is used to add minus sign is number < 0 and "+" is to add plus if >0
for that "+" itself is enough.
yeah i got it ....
