simple 2+2 not so simple at all

HI, the answer is: package com.codegym.task.task01.task0128; /* As simple as 2+2 */ public class Solution { public static void main(String[] args) { //write your code here int a = 2; int b = 2; sum(a,b); } public static void sum(int a, int b) { int c = a + b; System.out.print(c); } } You're welcome ;)

It's not a java syntax issue. It's just you breaking two of the four rules: "The main method should not call a screen output method." You are doing that with

System.out.println(2+2)

"The main method should call the sum method with the arguments 2 and 2." See the above.

System.out.println(c); //rather than: System.out.print(c);

package com.codegym.task.task01.task0128;
/* As simple as 2+2 */
public class Solution {
  public static void main(String[] args) { sum(2,2); }
  public static void sum(int a, int b) { int c = a + b; System.out.print(c); }
}
