Java Format negative Integer

Question

I try to format integers so they always have four proper digits, that is, I want 0s for padding.

I have tried "%04d" which works nicely for positive number. For negatives it gives things like -[854] where I need -[0854].

Thank you.

(you may be confused with the above comment. You can try explaining more, that is, `int i=1;System.out.printf("%04d",i);` instead of just `"%04d"`) — user202729, May 20 '18 at 06:35

(wait, that's C, but it also works here, use `"% 05d"`, see the 4th flag [here](https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html#syntax)) — user202729, May 20 '18 at 06:40

if(number>=0){ 
    String.format("%04d",number); 
}else{
     String.format("%05d",number); 
    }
