Question

All Codes are in java, I need the answers asap my assignment is almost due, thanks. I'll give thumbs up.

5. (20 pts)Given the Abstract class below, Shape, draw the UML diagram for a class Square that inherits Shape. Square needs to contain a private variable called side which is a double. It should have a default no argument constructor and an overloaded constructor that takes color, filled and side. Shape -color: String -filled: boolean +Shape() +Shape(color: String, filled: boolean) +getColor():String +isFilled(): boolean +getArea(): double +getPerimeter(): double

Answer 1

Shape -color: String - filled: boolean + Shape() + Shape(color: String, filled: boolean) + getColor(): String + isFilled(): boolean + getArea(): double + getPerimeter(): double Square - side: double + Square + Square(color: String, filled: boolean, side: double) + getSide(): double + getArea(): double + getPerimeter(): double

Shape.java

public abstract class Shape {
   private String color;
   private boolean filled;
  
   public Shape() {}
  
   public Shape(String color, boolean filled) {
       this.color = color;
       this.filled = filled;
   }

   public String getColor() {
       return color;
   }

   public boolean isFilled() {
       return filled;
   }
  
   public abstract double getArea();
   public abstract double getPerimeter();
}

Square.java

public class Square extends Shape{
  
   private double side;
  
   public Square() {}
  
   public Square(String color, boolean filled, double side) {
       super(color, filled);
       this.side = side;
   }

   public double getSide() {
       return side;
   }

   @Override
   public double getArea() {
       return this.side*this.side;
   }

   @Override
   public double getPerimeter() {
       return 4*(this.side);
   }
}
