Hands-On Design Patterns with Java

TypeA classes

Our solution includes a Factory class for each of the three types of motor homes (type A, type B, and type C). The TypeAFactory class shown in the following code extends the MotorHomeAbstractFactory class:

public class TypeAFactory extends MotorHomeAbstractFactory {    public Frame createFrame() {        return new TypeAFrame();    }    public Style createStyle() {        return new TypeAStyle();    }    public Engine createEngine() {        return new TypeAEngine();    }    public Kitchen createKitchen() {        return new TypeAKitchen();    }}

In addition to a Factory class, we need a class to implement the class hierarchy. Here, you see can each of the interfaces that were implemented:

public class TypeAStyle implements Style {    public String getStyle() {        return "[Type A] ...
