formatting

.......i have doubt in formatting

int i1 = -123;
int i2 = 12345;

System.out.printf(">%0,7d< \n", i2);
System.out.format(">%+-7d< \n", i2);

result is

>012,345<
>+12345 <

can you explain me this......how did the comma go between 012 and y the - symbol was not inserted....

thanks...

The - symbol was not printed since you are printing a positive integer (i2 is greater than zero)
and when the comma symbol is used to format the numbers, typically comma separates group of 3 digits from the RHS. Thus, 1234567 will be printed as 1,234,567

thanks for the reply...but i din get the concept of i2 greater than zero....

When you use the - symbol , if you're printing a negative number .. it'll be printed inside parenthesys

    
 
int i3 = -5355;
 
System.out.format(">%-d< \n", i3);
 

result is

>(5355)<

Hope this helps...

that happens when you use "(" this symbol..... - will jus insert - i guess
