I don't know how to call a method from another class?

Question

Java

The bottom line is that I have to call the method NOT through the object, I have already tried many times, here are my successes: (it gives errors everywhere)

public class Arithmetic {
  static boolean check(int[] array) {
        }
}
public class Demo {
  public static void main(String[] args) {
    check([4]); 
                boolean check(); 
                и тд хелп ребята
        }
}

Answer 1

Arithmetic.check(new int[] { 4 });
You should read a textbook.
