[Solved]Create Java Class Output Would Come Input X Y R 1 2 3 User Puts Number Input Type 1 Circle Q37254306

create java class

output would come out as this:

Input x,y,r

1 2 3 // user puts any number here

Input type -1: Circle | 2:triangle | 3:square | others:polygon

1//user selects number

Polygon’s area is 0.0

triangle area

circle area

square area

here is the code that I’m going to use

class Point {
private int x;
private int y;
public Point(int x, int y) {
this.x = x;
this.y = y;
}
public int getX() {
return this.x;
}
  
public int getY() {
return this.y;
}
}

class Polygon {
protected Point center;
   protected double radius;
   protected double area;

   public Polygon(Point cent, double r) {
       this.center = newPoint(cent.getX(), cent.getY());
       this.radius = r;
this.area = 0;

   }
  
   public Point getCenter() {
       return newPoint(this.center.getX(),
          this.center.getY());
   }
  
   public double getRadius() {
       return this.radius;
   }
  
   public void explain() {
       System.out.println(“This ispolygon.”);
       System.out.println(“Center : [” +center.getX() + “, ” + center.getY() + “]”);
       System.out.println(“Radius : ” +radius);
   }
public String toString() {
   return “Polygon’s area is ” + this.area;
   }
}

class Circle extends Polygon {
public Circle(Point p, double r) {
// create code
}
  
public void explain() {
// create code
}
}

class Triangle extends Polygon {
public Triangle(Point p, double r) {
// create code
}
  
public void explain() {
// create code
}
}

class Square extends Polygon {
public Square(Point p, double r) {
// create code
}
  
public void explain() {
// create code
}
}

class Main {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
       int x = 0, y = 0, type = 0;
       double r = 0;
       Polygon p;
      
       System.out.println(“Input x, y,r”);
       x = keyboard.nextInt();
       y = keyboard.nextInt();
       r = keyboard.nextDouble();
      
       System.out.println(“Input type – 1:circle | 2: triangle |
                      3: square| others: polygon”);
       type = keyboard.nextInt();
      
       // create code
       // Don’t use System.out.println athere.
       // System.out.println should beplaced on explain function.
      
       p.explain();
      
       keyboard.close();
}
}
