Please help with this

The Movie class will now implement Comparable. In your answer below, show the new class header for Movie and then implement the compareTo method as follows:

movie objects should be ordered based on title and then year

Solution

Hi Friend, Please find my implementation.

Please let me know in case of any issue.

public class Movie implements Comparable<Movie> {

   private String title;

   private int year;

   // others instance members

   // implementation of compareTo method

   @Override

   public int compareTo(Movie o) {

       if(title.compareTo(o.title) < 0)

           return -1;

       else if(title.compareTo(o.title) > 0)

           return 1;

       else{ // title is equal so sort based on year

           if(year < o.year)

               return -1;

           else if(year > o.year)

               return 1;

           else

               return 0;

       }

   }

}
