I'm trying to change the value of static variable that I passed to `Klasa.method()` function and sadly return value is ignored.

```java
package com.company;

public class Klasa {
    public static int metoda(int x){
        x += 2;
        return x;
    }

}

public class Main {
    public static int i = 10;

    public static void main(String... args) {
        System.out.println(Main.i);
        Klasa.metoda(i);
        System.out.println(Klasa.metoda(i));
        System.out.println(i);
    }
}

```
