In addition to the way you have defined the needed constructors, you also need to define methods to determine the sale price, such as:     public double getSalePrice() {         if (length > 20)           salePrice = regularPrice * 0.95;         else           salePrice = regularPrice * 0.90;         return salePrice; Then, you could determine the sale price of a Sedan, as follows:     Sedan sedan1 = new Sedan (120, 25000.00, "red", 25);     System.out.println ("Sedan's Sale Price:" + sedan1.getSalePrice()); Shawn Ayromloo Rafał Laczek wrote: Hi, I have some problems with MyOwnShop class with the main() method. In each class I have following constructors: //Creates a new instance of Car public Car(int speed, double regularPrice, String color ){ this.speed=speed; this.regularPrice=regularPrice; this.color=color; } //Creates a new instance of Ford public Ford(int speed,double regularPrice, String color, int year, int manufacturerDiscount){ super(speed, regularPrice, color); this.year=year; this.manufacturerDiscount=manufacturerDiscount; } //Creates a new instance of Sedan public Sedan(int speed,double regularPrice, String color, int lenght){ super(speed, regularPrice, color); this.lenght=lenght; } Should I rebuild the project and put these constructors into MyOwnAutoShop class? but if these constructors should stay in current classes how I should initialize all fields with values and how to use super(). I have some mish-mash in my head with it. Can somebody help me. Thanks Best regards, Rafał Laczek ---------------------------------------------------- Marzysz o karierze modelki?
