What will be printed when the program is executed?

public class FirstClass {
    int x = 1;
}

class SecClass extends FirstClass {
    int x = 15;
    
    void printNum() {
        System.out.println("x is " + x);
        System.out.println("x is also " + super.x);
    }
    
    public static void main(String[] args) {
        new SecClass().printNum();
    }
}
