Practice for inheritance

Practice for inheritance

1. Create a class circle and use inheritance to create another class cylinder from it
2. Create a class rectangle and use inheritance to create another class cuboid, try to keep it as close to the real-world scenario as possible (for your practice) 
3. Create a method for area and volume in 1 
4. create methods for area & volume in 2 and also create getters and setters 
5. What is the order of constructor execution for the following inheritance hierarchy 

Code:

package Com.Suryawanshi;
class Circle{
    int radius;

    public int getRadius() {
        return radius;
    }

    public void setRadius(int radius) {
        this.radius = radius;
    }

    Circle(){
        System.out.println("I am Non Parametrized Constructor");
    }

    Circle(int r){
        this.radius=r;
    }

    public double circleArea(){
        return Math.PI*this.radius*this.radius;
    }

}
class Cylender extends Circle{
    int height;

    public int getHeight() {
        return height;
    }

    public void setHeight(int height) {
        this.height = height;
    }

    Cylender(int r, int h){
        super(r);
        this.height=h;
    }

    public double cylenderVolume(){
        return Math.PI*this.radius*this.radius*this.height;
    }

}
public class Inheritance1 {
    public static void main(String[] args) {
        Cylender volume = new Cylender(12,5);
        System.out.println("Area of Circle is "+volume.circleArea());
        System.out.println("volume of Circle is "+volume.cylenderVolume());

    }
}
