Hands-On Design Patterns with Java

TypeB classes

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

public class TypeBFactory extends MotorHomeAbstractFactory {    public Frame createFrame() {        return new TypeBFrame();    }    public Style createStyle() {        return new TypeBStyle();    }    public Engine createEngine() {        return new TypeBEngine();    }    public Kitchen createKitchen() {        return new TypeBKitchen();    }}

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

public class TypeBStyle implements Style {    public String getStyle() {        return "[Type B] Style:\t\tWeekender";    }}public ...
