I need help With this problem for JAVAFX. if possible can it work in eclipse.
GeometricObjects code
public abstract class GeometricObject { private String color = "white"; private boolean filled; private java.util.Date dateCreated; /** Construct a default geometric object */ protected GeometricObject() { dateCreated = new java.util.Date(); } /** Construct a geometric object with color and filled value */ protected GeometricObject(String color, boolean filled) { dateCreated = new java.util.Date(); this.color = color; this.filled = filled; } /** Return color */ public String getColor() { return color; } /** Set a new color */ public void setColor(String color) { this.color = color; } /** Return filled. Since filled is boolean, * the get method is named isFilled */ public boolean isFilled() { return filled; } /** Set a new filled */ public void setFilled(boolean filled) { this.filled = filled; } /** Get dateCreated */ public java.util.Date getDateCreated() { return dateCreated; } @Override public String toString() { return "created on " + dateCreated + "\ncolor: " + color + " and filled: " + filled; } /** Abstract method getArea */ public abstract double getArea(); /** Abstract method getPerimeter */ public abstract double getPerimeter(); }
GeometricObjectComparator
import java.util.Comparator; public class GeometricObjectComparator implements Comparator<GeometricObject>, java.io.Serializable { public int compare(GeometricObject o1, GeometricObject o2) { return o1.getArea() > o2.getArea() ? 1 : o1.getArea() == o2.getArea() ? 0 : -1; } }
the error i get is in one of the pictures.
![Write the following generic method using selection sort and a comparator:

Step 1
We have been given GeometricObject[] list1 = {new Circle (5), new Rectangle(4, 5),
new Circle(5.5), new Rectangle(2.4, 5), new Circle(0.5),
new Rectangle(4, 65), new Circle(4.5), new Rectangle(4.4, 1),
new Circle(6.5), new Rectangle(4, 5)}; We have to create a test program that creates an array of 10 GeometricObjects and invokes this method using the GeometricObjectComparator.
