what should be the solution of this problem?

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) {
//write your code here
printCircleCircumference=2*pi*radius;
double pi =3.14;
System.out.println("the result is"+printCircleCircumference(int radius));
}
}
