When b.foo(5) is called in the main method, what is printed?

class A {
    public void foo(int x) {
        System.out.println("A");
    }
}

class B extends A {
    public void foo(double x) {
        System.out.println("B");
    }
}

public class Test {
    public static void main(String[] args) {
        B b = new B();
        b.foo(5);
    }
}
