有一个农场公司，专门向市场销售各类水果，主要包括下列水果：葡萄 Grape，草莓 Stuawberry，苹果 Apple；有一个Fruit接口，包含grow生长，harvest收获和plant方法，

package com.a;


public class Test16 {
    public static void main(String[] args) {
        Fruit fruit = FruitGardener.etFruit("apple");
        fruit.plant();
        fruit.grow();
        fruit.harveat();
        Fruit fruit2 = FruitGardener.etFruit("Strawberry");
        fruit2.plant();
        fruit2.grow();
        fruit2.harveat();
        Fruit fruit3 = FruitGardener.etFruit("grape");
        fruit3.plant();
        fruit3.grow();
        fruit3.harveat();
    }
}
