一个专一工厂模式的农场(青铜形态-简单工厂模式)

如今的农场有三种水果：Grape、Strawberry、Apple.

一名园丁在管理整个农场，向市场提供现有的水果：

public class FruitGardener {
    public static Fruit factory(String which)throws NoFruitException{
        if(which.equalsIgnoreCase("apple")){
            return new Apple();
        }else if(which.equalsIgnoreCase("grape")){
            return new Grape();
        }else if(which.equalsIgnoreCase("strawberry")){
            return new Strawberry();
        }else{
            throw new NoFruitException("Wrong fruit request!");
        }
    }
}
public class NoFruitException extends Exception {
   public NoFruitException(String msg){
     super(msg);
   }
}
水果都是这样的.水果接口：
public interface Fruit {
    //生长
    void grow();
    //收获
    void harvest();
    //种植
    void plant();
}

苹果是这样的：

public class Apple implements Fruit{
    public void grow() {
        System.out.println("Apple is growing...");
    }
    public void harvest() {
        System.out.println("Apple has been harvested.");
    }
    public void plant() {
        System.out.println("Apple has bean planted.");
    }
}
葡萄是这样的：
public class Grape implements Fruit{
    public void grow() {
        System.out.println("Grape is growing...");
    }
    public void harvest() {
        System.out.println("Grape has bean harvested.");
    }
    public void plant() {
        System.out.println("Grape has bean planted.");
    }
}

草莓是这样的：
public class Strawberry implements Fruit{
    public void grow() {
        System.out.println("Strawberry is growing...");
    }
    public void harvest() {
        System.out.println("Strawberry has bean harvested.");
    }
    public void plant() {
        System.out.println("Strawberry has bean planted.");
    }
}
市场是这样的：
try{
    FruitGardener.factory("grape");
    FruitGardener.factory("Apple");
    FruitGardener.factory("strawberry");
}catch(NoFruitException ex){
           
}
最近香蕉价格涨停，可是这个园丁不会种，老板考虑是换一个园丁或者让这个园丁去osc培训种香蕉呢？不管如何加班是必定的了
