(Solved) : Java Project 10 Design Class Named Triangle Extends Abstract Class Geometricobject Import Q28247553 . . . .

Java Project 10  

Design aclass  namedTriangle that extends the abstractclass  GeometricObject:

importjava.util.Scanner;

abstractclass  GeometricObject{
private  Stringcolor = “white”;
private  booleanfilled;
private  java.util.DatedateCreated;

/** Construct adefault geometricobject */
protected GeometricObject(){
}

/** Construct ageometric object with color andfilled value */
protectedGeometricObject(Stringcolor, boolean filled) {
dateCreated = newjava.util.Date();
this.color = color;
this.filled = filled;
}

/** Return color */
publicString  getColor(){
return color;
}

/** Set a new color */
public voidsetColor(Stringcolor) {
this.color = color;
}

/** Return filled. Since filled is boolean ,
* the get method isnamed  isFilled*/
publicboolean  isFilled(){
return filled;
}

/** Set a new filled */
public void setFilled(booleanfilled) {
this.filled = filled;
}

/** Get dateCreated */
publicjava.util.DategetDateCreated() {
return dateCreated;
}

@Override
public String toString() {
return “created on ” + dateCreated+ “ncolor: ” + color+
” and filled: ” + filled;
}

/** Abstractmethod  getArea*/
public abstractdouble  getArea();

/** Abstractmethod  getPerimeter*/
public abstractdouble  getPerimeter();
}

The Triangle classcontains:

Three double datafields named side1, side2,
