hashCode() and equals()

Here's a class named BlackBox. The class has equals and hashCode methods.

What does this code output?

Tip: Class BlackBox doesn't override equals method.

public class BlackBox {

    private final int additive;
    private int input1;
    private int input2;

    public BlackBox(int add){
        additive = add;
    }

    @Override
    public int hashCode() {
        return super.hashCode();
    }


    public boolean equals(BlackBox obj) {
        if (this == obj) return  true;

        if (!(obj instanceof BlackBox)) return false;

        BlackBox that = (BlackBox) obj;

        return (additive == that.additive)
                &&
                (input1 == that.input1)
                &&
                (input2 == that.input2);
    }


    public static void main(String[] args) {

        BlackBox bb1 = new BlackBox(11);
        Object bb2 = new BlackBox(11);

        System.out.print(bb1.equals(bb2) + " ");
        System.out.print(bb2.equals(bb1));
    }
}
