Java - attribute missing when using super in child class

I'm creating some Java code of an array of Flying Objects, which all have an attribute price (double). I am somewhat new to inheritance and this is is my first time using the super keyword. When I create a child class object Airplane into the array, the price feature does not seem to properly pass through the constructor.

Here are my FlyingObject constructors:

public class FlyingObject {

protected double price;

public FlyingObject()
{
	price = 0;
}

public FlyingObject(double aPrice)
{
	price = aPrice;
}

and here are my Airplane constructors:

// CONSTRUCTORS

public Airplane ()
{
	super();
	brand = "Unknown brand";
	horsepower = 0;
}

public Airplane (String aBrand, double aPrice, int aHorsepower)
{
	super(aPrice);
	brand = aBrand;
	horsepower = aHorsepower;
}

Everything when I create the airplane with arguments String, double and int, the string (brand) and int (horsepower) get registered correctly, but the price stays at 0. Is there something I am doing obviously wrong that I am missing? Any help would be greatly appreciated.

EDIT: Found what I did wrong.Silly mistake.

In my Airplane class, I had redefined price as an instance variable and had forgot about it, which overwrote the price from FlyingObjects.

As soon as I took out that extra price variable and only had the price variable come from the superclass (as intended) then everything worked fine.

Will post better examples (reproducible) next time. Cheers

I'm not really sure what the issue you're having is. I just tried it out in jshell, and it seems to work pretty well:

public class FlyingObject {
    protected double price;

    public FlyingObject() { price = 0; }

    public FlyingObject(double aPrice) { price = aPrice; }
}

public class Airplane extends FlyingObject {
    int horsepower;
    String brand;

    public Airplane() { 
        super(); 
        brand = "Unknown brand";
        horsepower = 0;
   }

   public Airplane(String aBrand, double aPrice, int aHorspower) {
        super(aPrice);
        brand = aBrand;
        horsepower = aHorsepower;
   }
}

If I then call Airplane plane = new Airplane("Boeing", 500000, 800); I get an Airplane object, the results of which are that plane.price = 500000.

Also just as an aside, you might want to consider (instead of aHorsepower, aBrand, etc.) just using horsepower and brand in your constructors, and then using the this keyword as follows:

public Airplane(String brand, double price, int horsepower) {
    super(price);
    this.brand = brand;
    this.horsepower = horsepower;
}
