I'm having a little problem with my class. It got to be something very easy, but I just cant find out the solution. Class Cuboid
works well, but the class Cube
is just not okey, I think I've used the super
method in a wrong way.
Just give me a little hint. Thank you in advance.
class Cuboid { constructor(length, width, height) { this.length = length; this.width = width; this.height = height; } get surfaceArea() { return (this.length * this.width + this.length * this.height + this.height * this.width) * 2; } get volume() { return this.length * this.width * this.height; } } class Cube extends Cuboid { constructor(length) { super(length); this.height = length; } }
Guys, why do you downvote my question? It's not really nice...
As I suggesting Cube is Cuboid with all 3 dimension equal. So there is 2 options to do it:
1.
class Cube extends Cuboid {
constructor(length) {
super(length, length, length);
}
}
2.
class Cuboid {
constructor(length, width, height) {
this.length = length || 0;
this.width = width || this.length;
this.height = height || this.width;
}
