We have not been taught how to call a method, so why are we being tested? i can't seem to progress past this point.
package com.codegym.task.task01.task0127;
/*
Square of a number
*/
public class Solution {
public static void main(String[] args) {
//write your code here
}
public static int sqr(int a) {
return a * a;
}
}
