Question

Design a class to overload a function volume() as follows: 

1. double volume (double R): with radius (R) as an argument, returns the volume of a sphere using the formula.
   V = 4/3 × 22/7 × R³
2. double volume (double H, double R): with height(H) and radius(R) as the arguments, returns the volume of a cylinder using the formula.
   V = 22/7 × R² × H
3. double volume (double L, double B, double H): with length(L), breadth(B) and Height(H) as the arguments, returns the volume of a cuboid using the formula.

Answer 1

class ShapesVolume {
public static double volume (double R) {
double V = 4.0 / 3, * 22.0 / 7 * Math.pow(R, 3);
return V;
}
public static double volume(double H, double R) {
double V = 22.0 / 7 * R * R * H ;
return V;
}
public static double volume (double L, double B, double H) {
double V = L * B * H;
return V;
}
}

Answer 2

import java.util.*; 
public class FQ23
{
double V;
double volume(double R)
{ V = 4.0 / 3 * 22.0 / 7 * Math.pow(R, 3);
return V;
}
double volume(double H, double R)
{V = (22.0 / 7.0) * Math.pow(R, 2) * (double) H;
return (float) V;
}
double volume(double L, double B, double H)
{V = L * B * H;
return (float) V;
} 
public static void main(String args[])
{Scanner scn = new Scanner(System.in);
double R, L, B, H;
FQ23 obj = new FQ23();

System.out.println("Enter the radius of the sphere");
R = scn.nextDouble();
System.out.println(obj.volume(R)); R
System.out.println("Enter the height and radius of the cylinder");
H = scn.nextDouble();
R = scn.nextDouble();
System.out.println(obj.volume(H, R));
System.out.println("Enter the length, breadth and height of the cuboid");
L = scn.nextDouble();
B = scn.nextDouble();
H = scn.nextDouble();
System.out.println(obj.volume(L, B, H));
}}
