Hello arvind

Add the below code before main method :

public static double cylinderV(double r,double l){
       double volume;
       velocity=3.14*(r*r)*l;

       return volume;
       }

Hope this will solve Your problem.

Hi Friend,

Try the following code:

import java.util.*;
import java.text.*;

class CalculateCyliderVolume
{
    public static void main(String[] args) 
    {   
        DecimalFormat df = new DecimalFormat("##.00");
        double PI=3.14;
        Scanner input=new Scanner(System.in);
        System.out.print("Enter Radius: ");
        double r=input.nextDouble();

        System.out.print("Enter Height: ");
        double h=input.nextDouble();

        double volume=PI*r*r*h;
        System.out.println("Volume of Cylinder: "+df.format(volume));
        }
}

Thanks
