Getter and Setter Question and Answer

1. Create a class cylinder and use Getter and Setter to set it's radius and height.

package com.ritesh;
class pj{
    private float radius;
    private  float height;
    public float getRadius(){
        return  radius;
    }
    public void setRadius(float n1){
        radius=n1;
    }
    public  float getHeight(){
        return height;
    }
    public void setHeight(float n2){
        height=n2;
    }
}

public class cylinder {
    public static void main(String[] args) {
        pj sc=new pj();
        sc.setRadius(3.14f);
        sc.setHeight(10f);
        System.out.println(sc.getRadius());
        System.out.println(sc.getHeight());
    }
}

1. Use question 1 and calculate surface area and volume of the cylinder by user Input.

package com.ritesh;

import java.util.Scanner;

class things{
    private  int radius;
    private  int volume;

    public int getRadius() {
        return radius;
    }

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

    public int getVolume() {
        return volume;
    }

    public void setVolume(int volume) {
        this.volume = volume;
    }
}

public class cylinder {
    public static void main(String[] args) {
       things sc=new things();
        System.out.println("Enter the value of Radius");
        Scanner keyword=new Scanner(System.in);
        double radius=keyword.nextDouble();
        System.out.println("Enter the height");
        double height=keyword.nextDouble();

       sc.setRadius((int) radius);
       sc.setVolume((int) height);
       double sur_area=2*Math.PI*radius*height+2*Math.PI*radius*radius;
        System.out.println("Surface area  "+sur_area);
        double volume=Math.PI*radius*radius*height;
        System.out.println("Volume of cylinder "+volume);
    }
}
