Design a class to overload a function volume() as follows:
Study this program carefully to understand the logic, output, and explanation in a structured way.
Design a class to overload a function volume() as follows:
double volume (double R) – with radius (R) as an argument, returns the volume of sphere using the formula.
V = 4/3 x 22/7 x R3
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 x R2 x H
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.
V = L x B x H
public class RansariVolume
{
double volume(double r) {
return (4 / 3.0) * (22 / 7.0) * r * r * r;
}
double volume(double h, double r) {
return (22 / 7.0) * r * r * h;
}
double volume(double l, double b, double h) {
return l * b * h;
}
public static void main(String args[]) {
RansariVolume obj = new RansariVolume();
System.out.println("Sphere Volume = " +
obj.volume(6));
System.out.println("Cylinder Volume = " +
obj.volume(5, 3.5));
System.out.println("Cuboid Volume = " +
obj.volume(7.5, 3.5, 2));
}
}Sphere Volume = 905.142857142857
Cylinder Volume = 192.5
Cuboid Volume = 52.5

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
