Calculate the circumference of a circle

Well, we have a plan. Let's implement it. First, implement a method that calculates the circumference of a circle. To do this, you need to write the correct formula in the method and specify the arguments. But what about pi, which we know is 3.141592... and so on to infinity? We'll keep things simple: let pi = 3.14.

I learned that i didn't have to use double for radius . Also if i looked closer i would have had answer sooner

This might come later but there hasn't been any discussion about why doubles are called doubles (eg. double precision).

What is wrong in my code? please suggest. package com.codegym.task.task01.task0129; /* Calculate the circumference of a circle */ public class Solution { public static void main(String[] args) { printCircleCircumference(5); } public static void printCircleCircumference(int radius) { double pi=3.14; double c = 2*pi*radius; System.Out.println(c);//write your code here } }
