Padding Strings with format method on Java

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    String s1 = sc.next();
    int x = sc.nextInt();

    PadLeft(s1);
    System.out.printf("%03d", x);
    System.out.println();

    PadRight(s1);
    System.out.printf("%03d", x);
}

private static void PadRight(String s)
{
    System.out.printf("%1$15s", s);
}

private static void PadLeft(String s)
{
    System.out.printf("%1$-15s", s);
}

15 represents the minimal width of the String

Input

Hello
12

Output

Hello          012
          Hello012
