Yup you are on the right track try java.text.SimpleDateFormat
push **MILLI** seconds into a java.util.Date use an appropriate for
DateFormat mySimpleFormat = new SimpleDateFormat( "somethign with h's, m's and
s' and maybe some colons" );
System.out.println( mySimpleDateFormat.format( new Date( mySeconds * 1000 ) ) );

Close enough?

Try the javaDocs.

Use java.text.DecimalFormat.

This may not be what you are looking for at all... but may help.

Cast your seconds to be an int.
Then
int hours = seconds/3600
// equals 9
int tempminutes = seconds%3600
// equals 3400
int minutes = tempminutes/60
// equlas 56
int seconds = tempminutes%60
// eqals 40
so you get 35800 seconds = 9 hours, 56 minutes, 40 seconds.
Format it in any way you like

Orbital Period = 23 hours, 56 minutes, and 29.0 seconds

This corresponds to 86189 seconds... not 35800.
