java向arrayList添加新对象不起作用

public abstract class Bee {
    static Hive hive = Garden.hive;
    protected int type;
    protected int age;
    protected int health = 3;

    protected int getType()
    {
        return type;
    }
    protected int getAge()
    {
        return age;
    }
    protected int getHealth()
    {
        return health;
    }

    protected void setAge(int age)
    {
        this.age = age;
    }
    protected void setType(int input)
    {
        this.type = input;
    }
    protected abstract boolean eat();
    protected abstract void anotherDay();  //the bees tasks for day (should include eat())

}


    public class Queen extends Bee {

    protected Queen()
    {
        setType(1);
    }
    protected int eggTimer = 0; // tracks when to add a new egg (not using age incase an external factor causes layEgg) 

    // removed code to avoid being too long 

    protected void layEgg() {
        Egg egg = new Egg();
        hive.addBee(egg); //fix??
        eggTimer = 0;
    }
}



        import java.util.ArrayList;

    class Hive {


        ArrayList<Bee> beeList = new ArrayList<Bee>();
        // code removed
        public int beeIndex; // used to know what the index of bee you are in is


        protected void addBee(Bee bee) { //Its running this and getting into the beelist.add(bee) but after there is nothing new in beeList.
            if (beeList.size() < 100) {
                beeList.add(bee);
            } else {
                System.out.println("Too many Bees to add more");
            }
        }

        // removed code to avoid being too long 

        protected void anotherDay() {
            int i = 0;
            for (Bee bee : beeList) {
                i++;
                bee.anotherDay();
                beeIndex = i;
            }
        }
    }

代码运行时没有任何错误，但当它到达layEgg方法时，它会自动向配置单元中的arrayList添加一个egg（扩展bee的另一个类）。它运行addBee方法并遍历beeList。添加，但它仍然没有添加对象。如有任何建议，将不胜感激

我删掉了一些代码，使文章缩短了layEgg在Queen中第三次调用另一天（）时的运行时间

public class Garden {
    static Hive hive = new Hive();
    protected int flowerIndex;
    ArrayList<Flower> flowerList = new ArrayList<Flower>();

    protected void anotherDay() {
        int i = 0;
        for (Flower flower : flowerList) {
            i++;
            flower.anotherDay();
            flowerIndex = i;
        }
    }

    protected void addHive(Hive hiveInput) {
        Hive hive = hiveInput;
    }

    protected void addFlower(Flower flowerInput) {
        Flower flower = flowerInput;
    }

    protected Flower getFlower(int input) {
        return flowerList.get(input);
    }

    protected Flower findFlower() // finds the size of the arrayList and then
                                    // creates a random number within the array
                                    // to use as an index
    {

        int listSize = flowerList.size();
        Random random = new Random();
        int index = random.nextInt(listSize);
        return flowerList.get(index);
    }

    protected int getFlowerListSize()
    {
        return flowerList.size();
    }

}
