What is a cylinder?
A geometrical figure with straight parallel sides and a circular cross-section. For detailed information check out the below definition.
What is the formula to find out the volume of a cylinder?
A : The basic formula in order to calculate the volume of cylinder as follows :
Volume: π × r² × h

import java.util.Scanner; class VolumeOfCylinder { public static void main(String args[]) { Scanner s= new Scanner(System.in); System.out.println("Enter the radius:"); double r=s.nextDouble(); System.out.println("Enter the height:"); double h=s.nextDouble(); double volume=((22*r*r*h)/7); System.out.println("volume of Cylinder is: " +volume); } } |
Output :

1 2 3 4 5 |
Enter the radius: 5 Enter the height: 10 volume of Cylinder is:785.40 |
Online execution tool for the above program #example -1
Here is the complete explanation of above java code. If you at the beginning stage, then you can check out the below tutorial. so that you will get an idea. If you know how the code works , then you can check out the rest of the examples with online compiler and execution tool.
|
1 |
import java.util.Scanner; |
– System read the input variables and pass the necessary methods to a new scanner.
|
1 |
class VolumeOfCylinder |
– It is a blueprint where objects are created within a class.
|
1 |
public static void main(String args[]) |
– The main function , convert the given string as an argument into different formats as like double . int , float.
|
1 |
Scanner s= new Scanner(System.in); |
– Read the input values, where system.in can read the values from your system(import java.util.scanner) JDK file.
|
1 |
System.out.println("Enter the radius:"); |
– Display the output values , in that whatever you were written.
|
1 |
double r=s.nextDouble(); |
– Where double is a datatype , which can store the particular values.
|
1 |
double volume=((22*r*r*h)/7); |
– The formula to find out the volume of a cylinder in java.
|
1 |
System.out.println("volume of Cylinder is: " +volume); |
– Output displayed here.

So, you got an idea how the above java program works to find the volume of a cylinder. Below is another example method to calculate the volume of a cylinder. The difference between the above example -1 when compared with the below example -2 is nothing but just a couple of syntax lines has been changed. The little difference is as, whereas scanner function is used in order to retrieve the input variables and store in a particular location until the program executes. Whereas here, ‘parse’ method is used to directly retrieve the details from the screen itself.
Compiler method in # CMD: java filename.java
Execution method in #CMD: java classname arguments
Here is the Example program # 2 – using command line argument

import java.util.Scanner; class VolumeOfCylinder1 { public static void main(String args[]) { double r=Double.parseDouble(args[0]); double h=Double.parseDouble(args[1]); double volume=((22*r*r*h)/7); System.out.println("volume of Cylinder is: " +volume); } } |
Here is the online execution tool for the above program to calculate the volume of a cylinder.
Here is another example method #3 to calculate the volume. In the following method, we used a return invoked method. Check it out.
