Second output must be true but it shows false

Question

I have to determine which rooms are larger and my codes are:

public class Apartment {

    private int room;
    private int squareMeters;
    private int pricePerSquareMeter;

    public Apartment(int rooms, int squareMeters, int pricePerSquareMeter) {
        this.room = room;
        this.squareMeters = squareMeters;
        this.pricePerSquareMeter = pricePerSquareMeter;
    }

    public boolean larger(Apartment otherApartment) {
        if (this.room > otherApartment.room) {
            return true;
        }
        return false;
    }

    public static void main(String[] args) {
        Apartment studioManhattan = new Apartment(1, 16, 5500);
        Apartment twoRoomsBrooklyn = new Apartment(2, 38, 4200);
        Apartment fourAndKitchenBronx = new Apartment(3, 78, 2500);

        System.out.println(studioManhattan.larger(twoRoomsBrooklyn));
        System.out.println(fourAndKitchenBronx.larger(twoRoomsBrooklyn));
    }

}

Output:

false
false

first output as you see is false, it is okay, second one is also false, but when we read these codes, we can easily see that second room must be true. And in this exercise we should get the output as following:

false
true

Can you explain where I mistake? With which ways may I achieve the correct output ?

Answer 1

You should change

public Apartment(int rooms, int squareMeters, int pricePerSquareMeter) {
        this.room = room; // Same as this.room = this.room, no effect at all.
        this.squareMeters = squareMeters;
        this.pricePerSquareMeter = pricePerSquareMeter;
    }

to

public Apartment(int rooms, int squareMeters, int pricePerSquareMeter) {
        this.room = rooms; // Typo was here.
        this.squareMeters = squareMeters;
        this.pricePerSquareMeter = pricePerSquareMeter;
    }
