Java Program to Find Volume and Surface Area of Sphere

This is the Java Program to Find the Surface Area and Volume of a Sphere.

Problem Description

Given the dimensions of a sphere, find out its surface area and volume.

Problem Solution

The surface area and volume of a sphere can be calculated using the formulas:

Surface Area = 4 * PI * (radius3) /3.
Volume = 4 * PI * (radius2).

Program/Source Code

Here is the source code of the Java Program to Find the Surface Area and Volume of a Sphere. The program is successfully compiled and tested using IDE IntelliJ Idea in Windows 7. The program output is also shown below.

  2. //Java Program to Find the Surface Area and Volume of a Sphere
  4. import;
  5. import;
  7. public class Sphere {
  8.     // Function to calculate and print the surface area and volume of a sphere
  9.     public static void main(String[] args) {
  10.         BufferedReader br = new BufferedReader(new InputStreamReader(;
  11.         double radius;
  12.         System.out.println("Enter the radius of the sphere");
  13.         try{
  14.             radius=Double.parseDouble(br.readLine());
  15.         }catch (Exception e){
  16.             System.out.println("An error occurred");
  17.             return;
  18.         }
  19.         if(radius<=0){
  20.             System.out.println("Wrong Input");
  21.             return;
  22.         }
  23.         System.out.println("Volume = " + (4*Math.pow(radius,3)*Math.PI)/3);
  24.         System.out.println("Surface area = " + (4*Math.PI*Math.pow(radius,2)));
  25.     }
  26. }
Program Explanation

1. In function main(), first, the radius of the sphere is taken as input.
2. The condition if(radius<=0) checks if the input is valid or not.
3. The print statement displays the surface area and volume of the sphere.


Time Complexity: O(1)

Runtime Test Cases
Case 1 (Simple Test Case):
Enter the radius of the sphere
Volume = 394.56885292638566
Surface area = 260.15528764377075
