Need help filling in the areas, unsure of how to do the code, JAVA. I've highlited what needs completing. 

 /** Sort Die objects using the interface Comparable and the classes ArrayList, Collections. The sorting is from small values to large (ascending). Todo: Make 120 Die objects, each with 100 sides. Throw each one Add the objects to the list. print the list Sort them using Collections.sort print the list */ import java.util.Collections ; import java.util.ArrayList ; import java.util.Random ; public class DieSorter { public static void main(String[] args) { Random random = new Random(1) ; ArrayList list = new ArrayList() ; for (int i = 0 ; i < 120 ; i++) { Die die = new Die(100, random) ; die.cast() ; list.add(die) ; } System.out.println(list) ; System.out.println("------------------------------------") ; Collections.sort(list) ; System.out.println(list) ; } } /** Die models a die that, when cast, lands on a random face Here the class is modified to implement Comparable. The sorting of the Die objects is from small values to large. Notice there is a new constructor that takes the number of sides and a random number generator as parameters -- you need that constructor for this problem. */ //-----------Start below here. To do: approximate lines of code = 1 // Write the "class Die ... " part so that Comparable is implemented, but leave out the public specifier since only one class in the file can be public. //-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions. { private Random random ; private int sides ; private int sideUp ; /** Constructs a die with a given number of sides @param sides the number of sides, e.g., 6 for normal die */ public Die(int sides) { this.sides = sides ; random = new Random() ; sideUp = 0 ; } /** Constructs a die with a given number of sides and gives the random object @param sides the number of sides, e.g., 6 for normal die @param random the random number generator */ public Die(int sides, Random random) { this.sides = sides ; this.random = random ; sideUp = 0 ; } /** Simulates a throw of a die @return the face of the die */ public int cast() { sideUp = 1 + random.nextInt(sides) ; return sideUp ; } /** Gives a String representation of the Die @return the sideUp as a string */ public String toString() { return "" + sideUp ; } /** Compares this die with another in form of Comparable interface. The sorting is from small values to larger values. @return 1 if this one has a bigger value, -1 if smaller, 0 if same */  //-----------Start below here. To do: approximate lines of code = 4 // 1. public signature ; //2. code for the -1 case ; //3. code for the 1 case ; //4. code for the 0 case.  //-----------------End here.
