Java console displaying address of object rather than actual value [duplicate]

Answer 1

What you want is to override toString() in your class House.

class House {
    // ... your implementation, 
    // which I'm guessing it's something like this:
    private int number;
    private int bottles;

    public House(int number, int bottles) {
        this.number = number;
        this.bottles = bottles;
    }

    // here you say what you want as output if you print a House, e.g.:
    @Override 
    public String toString() {
        return String.valueOf(bottles);
    }
}
