Java Program to Find Volume of Cylinder

import java.util.*;
public class Main
{  
    public static void main(String args[])  
    {  
    //height of cylinder declared
    int height=8;  
    //radius of cylinder declared
    int radius=5; 
    //pie vlaue declared
    double pie=3.14285714286;
    //calculating volume of cylinder
    double volume = pie * radius * radius * height;  
        System.out.println("Volume of cylinder="+volume);  
    }  
}

Output:

Volume of cylinder=628.5714285720001
