模拟一个汽车工厂生产汽车解题提示a)可生产大卡车、大客车、小汽车、跑车等b)不同的车售价不同c)涉及知识点有类、接口、继承、封装、多态提示：运用工厂模式的设计模式去做

public interface ICar {

  void price();
} 

 public class Coach implements ICar {
  @Override
  public void price() {
    System.out.printf("2000万");
  }
}

 public class Truck implements ICar {
  @Override
  public void price() {
    System.out.printf("1000万\n");
  }
}

 public class SUV implements ICar {
  @Override
  public void price() {
    System.out.printf("40万");
  }
}

 public class CarFactory {

  public static final int TYPE_TRUCK = 1;
  public static final int TYPE_COACH = 2;
  public static final int TYPE_SUV = 3;

  public ICar createCar(int type) {
    if (type == TYPE_COACH) {
      return new Coach();
    } else if (type == TYPE_TRUCK) {
      return new Truck();
    } else if (type == TYPE_SUV) {
      return new SUV();
    } else {
      // TODO 其他的车
    }
  }
}
