设计模式快速参考－简单工厂模式

abstract class Fruit{
}


class Apple extends Fruit{
}


class Orange extends Fruit{
}


class FruitFactory{
   pulic static Fruit getFruit(String fruitType){
      if (“apple” == fruitType){
         return new Apple();
      } else if (“orange” == fruitType) {
         return new Orange();
      }
   }
}
