Question

write a menu driven program using user's choice to perform the following operations volume of a cube is equals to s * s * s volume of a sphere is equals to 4/3 * 22/7*r*r*r volume of a cuboid is equals to l * b *h​

Answer 1

Answer:

import java.util.*;

class hlo

{

public static void main (String args [])

{

Scanner sc=new Scanner (System.in);

System.out.println("Enter 1 for cube");

System.out.println("Enter 2 for sphere");

System.out.println("Enter 1 for cuboid");

int ch=sc.nextInt();

switch (ch)

{

case 1:

System.out.println("Side");

int s=sc.nextInt();

int v=s*s*s;

System.out.println("Volume of cube="+v);

break;

case 2:

System.out.println("Radius");

int r=sc.nextInt();

double v1= (4/3)*(22/7)*r*r*r;

System.out.println("Volume of sphere="+v1);

break;

case 3:

System.out.println("Enter Length");

int l=sc.nextInt();

System.out.println("Enter breadth");

int b=sc.nextInt();

System.out.println("Enter Height");

int h=sc.nextInt();

int v2=l*b*h;

System.out.println("Volume of cuboid="+v2);

break;

default :

System.out.println("Wrong input");

}

}

}
