(Solved) : M Confused Help Define Class Named Comparabletriangle Extends Triangle Implements Comparab Q30470231 . . .

I’m confused. Help me out!!!

Define a class named ComparableTriangle thatextends Triangle and implementsComparable. Draw the UML diagram and implementsthe compareTo method to compare the triangles onthe basis of area. Write a test class to find the larger of twoinstances of ComparableTriangle objects. Be sureto accept only valid triangles.

These are what I made so far.

public abstract class GeometricObject {

private String color = “white”;
private boolean filled;
private java.util.Date dateCreated;

//construct for a geometric object
public GeometricObject() {
dateCreated = new java.util.Date();
}

//constructor with color
public GeometricObject(String color, boolean filled) {
dateCreated = new java.util.Date();
this.color = color;
this.filled = filled;
}

//return color
public String getColor() {
return color;
}

//return color
public void setColor(String color) {
this.color = color;
}

//return filled
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;
}

//return to a string
public String toString() {
return “created on ” + dateCreated + “ncolor: ” + color
+ ” and filled: ” + filled;
}

}
