类型：创建模式
定义一个用于创建对象的接口，让其子类来决定实例化哪一个类（产品），工厂方法使一个类的创建延迟到其子类中。
模式UML图
实现代码如下:
新建赛车的接口：
package car_interface;
public interface Icar_interface {
public void start();
public void stop();
}
新建1个汽车信息的基类：
package car_imple;
import car_interface.Icar_interface;
public class base_car_imple implements Icar_interface {
private int speed;
private String name;
public int getSpeed() {
return speed;
}
public void setSpeed(int speed) {
this.speed = speed;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public void start() {
// TODO Auto-generated method stub
}
public void stop() {
// TODO Auto-generated method stub
}
}
新建奥迪汽车实现类：
package car_imple;
import car_interface.Icar_interface;
public class car_audi_imple extends base_car_imple {
public void start() {
System.out.println(this.getName() + " 车以专利技术起动了 最高速度为："
+ this.getSpeed());
}
public void stop() {
System.out.println(this.getName() + " 车以专利技术停车了");
}
}
新建大众汽车实现类：
package car_imple;
import car_interface.Icar_interface;
public class car_3w_imple extends base_car_imple {
public void start() {
System.out.println(this.getName() + " 车以专利技术起动了 最高速度为："
+ this.getSpeed());
}
public void stop() {
System.out.println(this.getName() + " 车以专利技术停车了");
}
}
新建一个汽车工厂接口：
package car_factory_interface;
import car_interface.Icar_interface;
public interface Icar_factory {
public Icar_interface create_car();
}
新建一个创建奥迪车的汽车工厂实现类：
package car_factory_imple;
import car_factory_interface.Icar_factory;
import car_imple.car_audi_imple;
import car_interface.Icar_interface;
public class audi_car_factory_imple implements Icar_factory {
public Icar_interface create_car() {
car_audi_imple car_audi_imple_ref = new car_audi_imple();
car_audi_imple_ref.setName("奥迪A6");
car_audi_imple_ref.setSpeed(300);
return car_audi_imple_ref;
}
}
新建一个创建大众车的汽车工厂实现类：
package car_factory_imple;
import car_factory_interface.Icar_factory;
import car_imple.car_3w_imple;
import car_imple.car_audi_imple;
import car_interface.Icar_interface;
public class threeW_car_factory_imple implements Icar_factory {
public Icar_interface create_car() {
car_3w_imple car_3w_imple_ref = new car_3w_imple();
car_3w_imple_ref.setName("大众A6");
car_3w_imple_ref.setSpeed(400);
return car_3w_imple_ref;
}
}
