What is the output when a new B() is instantiated in the above code?

class A {
    A() { overrideMe(); }
    void overrideMe() { System.out.println("A"); }
}

class B extends A {
    int x = 5;
    B() { }
    @Override
    void overrideMe() { System.out.println("B: " + x); }
}

public class Main {
    public static void main(String[] args) { new B(); }
}
