類型：創建模式
定義一個用於創建對象的接口，讓其子類來決定實例化哪一個類（產品），工廠方法使一個類的創建延遲到其子類中。
模式UML圖
實現代碼如下:
新建賽車的接口：
package car_interface;
public interface Icar_interface {
public void start();
public void stop();
}
新建1個汽車信息的基類：
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
}
}
新建奧迪汽車實現類：
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() + " 車以專利技術起動了 最高速度爲："
+ this.getSpeed());
}
public void stop() {
System.out.println(this.getName() + " 車以專利技術停車了");
}
}
新建大衆汽車實現類：
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() + " 車以專利技術起動了 最高速度爲："
+ this.getSpeed());
}
public void stop() {
System.out.println(this.getName() + " 車以專利技術停車了");
}
}
新建一個汽車工廠接口：
package car_factory_interface;
import car_interface.Icar_interface;
public interface Icar_factory {
public Icar_interface create_car();
}
新建一個創建奧迪車的汽車工廠實現類：
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("奧迪A6");
car_audi_imple_ref.setSpeed(300);
return car_audi_imple_ref;
}
}
新建一個創建大衆車的汽車工廠實現類：
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("大衆A6");
car_3w_imple_ref.setSpeed(400);
return car_3w_imple_ref;
}
}
