Arrays class

How can i use Arrays.sort on an object's attribute, e.g.

Quote:

---

public class Movie{

public Movie (String title, int duration)
{...}
}//end class Movie

---

how can i do this:
Arrays.sort(Movie.duration, 20);

??

Movie.duration is invalid considering there is a 1 dimensional array Movie

EASY SOLUTION:
break the array Movie in 3 arrays each holding an attribute of a movie but i want to keep the search on the object Movie specific to 1 of its attributes
