Java
抽象工厂模式
- 用来生产不同产品族的全部产品。(对于增加新的产品，无能为力；支持增加产品族)
- 抽象工厂模式是工厂方法模式的升级版本，在有多个业务品种、业务分类时，通过抽象工厂模式产生需要的对象是一种非常好的解决方式。
1.
// 发动机接口
public interface Engine {
void run();
void start();
}
// 高级发动机
class LuxuryEngine implements Engine{
@Override
public void run() {
System.out.println("转的快!");
}
@Override
public void start() {
System.out.println("启动快!");
}
}
// 低级发动机
class LowEngine implements Engine {
@Override
public void run() {
System.out.println("转的慢!");
}
@Override
public void start() {
System.out.println("启动慢!");
}
}

// 发动机接口

3.
// 轮胎
public interface Tyre {
void revolve();
}
// 高级轮胎
class LuxuryTyre implements Tyre {
@Override
public void revolve() {
System.out.println("旋转不磨损!");
}
}
// 低级轮胎
class LowTyre implements Tyre {
@Override
public void revolve() {
System.out.println("旋转磨损");
}
}

// 造车工厂接口
public interface CarFactory {
Engine createEngine();
Seat createSeat();
Tyre createTyre();
}
// 制造高级车
public class LuxuryCarFactory implements CarFactory {
@Override
public Engine createEngine() {
return new LuxuryEngine();
}
@Override
public Seat createSeat() {
return new LuxurySeat();
}
@Override
public Tyre createTyre() {
return new LuxuryTyre();
}
}
// 制造低级车
public class LowCarFactory implements CarFactory {
@Override
public Engine createEngine() {
return new LowEngine();
}
@Override
public Seat createSeat() {
return new LowSeat();
}
@Override
public Tyre createTyre() {
return new LowTyre();
}
}

private void test() {
CarFactory factory = new LuxuryCarFactory();
Engine engine = factory.createEngine();
engine.run();
engine.start();
}
