## Program to Find Volume of Cylinder

Before going into the program, let’s see how we find the volume of cylinder.

Formula for Volume of Cylinder = pie * (r*r) * h

Where,

• r‘ represents the radius of cylinder.
• h‘ represents the height of cylinder.

Let’s see different ways to find volume of cylinder.

Provided list of Simple Java Programs is specially designed for freshers and beginners to get familiarize with the concepts of Java programming language and become pro in coding.

Approach:

1. Take input/declare the height, radius of cylinder.
2. Then calculate the volume by using the formula.

### Method-1: Java Program to Find Volume of Cylinder By Using Static Value

import java.util.*;

public class Main
{
public static void main(String args[])
{
//height of cylinder declared
int height=8;
//pie vlaue declared
double pie=3.14285714286;
//calculating volume of cylinder
System.out.println("Volume of cylinder="+volume);
}
}
Output:

Volume of cylinder=628.5714285720001

### Method-2: Java Program to Find Volume of Cylinder By User Input Value

import java.util.*;

public class Main
{
public static void main(String args[])
{
Scanner sc = new Scanner(System.in);

// Take height input from user
System.out.println("Enter Height of Cylinder");
double height = sc.nextDouble();

// Take radius input from user
System.out.println("Enter radius of Cylinder : ");

//pie vlaue declared
double pie=3.14285714286;

//calculating volume of cylinder
System.out.println("Volume of cylinder="+volume);
}
}
Output:

Enter Height of Cylinder : 8
Enter radius of Cylinder : 5
Volume of cylinder=628.5714285720001

### Method-3: Java Program to Find Volume of Cylinder By User Defined Method

import java.util.*;

public class Main
{
public static void main(String args[])
{
Scanner sc = new Scanner(System.in);

// Take height input from user
System.out.println("Enter Height of Cylinder : ");
double height = sc.nextDouble();

// Take radius input from user
System.out.println("Enter radius of Cylinder : ");
//findVolume() method called to find volume of cylinder
}

//findVolume() method
public static void findVolume(double height,double radius)
{
//pie vlaue declared
double pie=3.14285714286;

//calculating volume of cylinder
System.out.println("Volume of cylinder="+volume);
}
}
Output:

Enter Height of Cylinder : 8
Enter radius of Cylinder : 5
Volume of cylinder=628.5714285720001
