Question

1) Write a functional program in Java that can calculate the volume and surface area of a sphere and a cube

2) Write a procedural program in Java that can calculate the volume and surface area of a sphere and a cube

3) Write an Object Oriented Program in Java that can find the volume and surface area of a sphere and cube

Answer 1

Procedural Program:

import java.util.*;

class Main {

public static void main(String[] args) {

double radius, side,SAsphere,VSphere,SAcube,Vcube;

Scanner sc=new Scanner(System.in);

System.out.println("Enter radius of sphere: ");

radius=sc.nextDouble();

System.out.println("Enter Side of cube: ");

side=sc.nextDouble();

SAsphere=3.14*4*radius*radius;

VSphere=(4/3)*3.14*radius*radius*radius;

SAcube=6*side*side;

Vcube=side*side*side;

System.out.println("Surface area of sphere is : "+SAsphere);

System.out.println("Volume of Sphere: "+VSphere);

System.out.println("Surface area of Cube is "+SAcube);

System.out.println("Volume of Cube: "+Vcube);

}

}

2)Functional Program:

import java.util.*;

class Main {

public static double volumeSphere(double radius){

return (4/3)*3.14*radius*radius*radius;

}

public static double SAsphere(double radius){

return 3.14*4*radius*radius;

}

public static double volumeCube(double side){

return side*side*side;

}

public static double SACube(double side){

return 6*side*side;

}

public static void main(String[] args) {

double radius, side,SAsphere,VSphere,SAcube,Vcube;

Scanner sc=new Scanner(System.in);

System.out.println("Enter radius of sphere: ");

radius=sc.nextDouble();

System.out.println("Enter Side of cube: ");

side=sc.nextDouble();

System.out.println("Surface area of sphere is : "+SAsphere(radius));

System.out.println("Volume of Sphere: "+volumeSphere(radius));

System.out.println("Surface area of Cube is "+SACube(side));

System.out.println("Volume of Cube: "+volumeCube(side));

}

}

3) Object Oriented:

import java.util.*;

class Calculation {

public static double volumeSphere(double radius){

return (4/3)*3.14*radius*radius*radius;

}

public static double SAsphere(double radius){

return 3.14*4*radius*radius;

}

public static double volumeCube(double side){

return side*side*side;

}

public static double SACube(double side){

return 6*side*side;

}

}

class Main{

public static void main(String[] args) {

Calculation cal=new Calculation();

double radius, side,SAsphere,VSphere,SAcube,Vcube;

Scanner sc=new Scanner(System.in);

System.out.println("Enter radius of sphere: ");

radius=sc.nextDouble();

System.out.println("Enter Side of cube: ");

side=sc.nextDouble();

System.out.println("Surface area of sphere is : "+cal.SAsphere(radius));

System.out.println("Volume of Sphere: "+cal.volumeSphere(radius));

System.out.println("Surface area of Cube is "+cal.SACube(side));

System.out.println("Volume of Cube: "+cal.volumeCube(side));

}

}
