All of the following statements about the if-else-if structure in the above code snippet are true except:

public class Main {
    public static void main(String[] args) {
        int num = 15;
        if (num < 10) {
            System.out.println("Less than 10");
        } else if (num < 20) {
            System.out.println("Between 10 and 20");
        } else {
            System.out.println("20 or more");
        }
    }
}
