java - System.out.printf format -

i have written down following code:

public class fractionofday {      public static double fractionofday(double h, double m, int s, char ) {         double y = -1;         if (a == 'p' && h == 12) {             double x = (h * 60 * 60) + (m * 60) + (s);              y = x / 86400;         } else if (a == 'p' && h != 12) {             double x = ( (h + 12) * 60 * 60) + (m * 60) + (s);             y = x / 86400;         } else if (a == 'a' && h == 12) {             double x = (m * 60) + (s);             y = x / 86400;         } else if (a == 'a' && h != 12) {             double x = ( (h) * 60 * 60) + (m * 60) + (s);             y = x / 86400;         }         return y;     }      public static void main(string[] args) {         system.out.println(fractionofday(12, 0, 0, 'p'));     } } 

it prints out fraction of day has passed 12 . how can make print such table using printf?

using calendar class

public static void main(string[] args) {   calendar c = calendar.getinstance();   system.out.format("%tl:%tm %tp %10.4f%n", c, c, c,      fractionofday(       c.get(calendar.hour),       c.get(calendar.minute),       c.get(calendar.second),      (calendar.am == c.get(calendar.am_pm)) ? 'a' : 'p')); }
