java - hive 模拟 : A counter of a type of bee returns unusually high numbers

Question

我正在构建 hive 模拟，并使用名为 workerBee 的二维数组。它有以下 6 个字段:beeId、Age、Type(egg = 1、larva = 2、pupa = 3、worker = 4、drone = 5)、PollenCollection、Eaten、Alive

模型简介:蜂王每天产卵(10 到 50 个卵)，并将它们添加到 hive 中。每天，有关蜜蜂的数据都会更新(它们的年龄和类型)。

对于过去的每一天，我都会打印 hive 状态，其中打印有关蜜蜂数量、出生、死亡等的信息。在模拟过程中的某些日子(开始时，例如第 6 至 10 天)，报告的幼虫数量为 1 天约 800 至 900 只。以下是处理打印和计数的代码:

    public static int layDailyEggs() {
        Random randomEggs = new Random();
        final int MAX_EGGS = 50;
        final int MIN_EGGS = 10;

        int x = randomEggs.nextInt((MAX_EGGS - MIN_EGGS) + 1) + MIN_EGGS;
        eggsLaid = x;//eggsLaid as a global variable to be used in printBeehiveStatus
        return x;//To pass as argument to addEggToHive
}
    public static void addEggToHive(int eggsLaid) {
        //Update the workerBee array with available slots
        //Traverse the 2D array and while beeId != 0, add eggs and update
        for (int i = 0; i < workerBee.length; i++) {

            if (workerBee[i][0] == 0 && eggsLaid > 0) {
                //Available space           
                workerBee[i][0] = i;//Update beeID
                workerBee[i][1] = 1;//Update age
                workerBee[i][2] = 1;//Update Type
                eggsLaid--;
        }
    }
}
    public static void countTypesOfBees() {
        //Initialize for each day
        totalEggsLaid = 0;
        numberOfBirths = 0;
        numberOfLarva = 0;
        numberOfPupa = 0;
        numberOfWorkerBees = 0;
        numberOfDrones = 0;

        //To call upon updating type of each bee
        for (int i = 0; i < workerBee.length; i++) {

            if(workerBee[i][2] == 1) {
                totalEggsLaid++;
            }else if(workerBee[i][2] == 2) {
                numberOfLarva++;
                numberOfBirths++;
            }else if(workerBee[i][2] == 3) {
                numberOfPupa++;
                numberOfBirths++;
            }else if(workerBee[i][2] == 4) {
                numberOfWorkerBees++;
                numberOfBirths++;
            }else if(workerBee[i][2] == 5) {
                numberOfDrones++;
                numberOfBirths++;
            }
        }
}
    //Method called once daily
    public static void metamorphose() {     
        numberOfDeaths = 0;
        Random random = new Random();

        for (int i = 0; i < workerBee.length; i++) {

            //Updating the type of bee based on age of Bee
            if(workerBee[i][1] == 4) {
                workerBee[i][2] = 2;            
            }else if (workerBee[i][1] == 10) {  
                workerBee[i][2] = 3;
            }else if(workerBee[i][1] == 20){
                //Probability for a drone to emerge is 10%(As per area under curve, should be less than or equal to 10%)
                double probability = random.nextDouble();
                if (probability <= 0.1) {   
                    workerBee[i][2] = 5;//Drone Bee
                }else{
                    workerBee[i][2] = 4;//Worker Bee        
            }
        }
        if (workerBee[i][1] == 35 || workerBee[i][1] == 56) {
            //Call a funeral
            funeral(i);
            numberOfDeaths++;
        }

    }
    countTypesOfBees();     
}
    //To be called at the end of the day
    public static void printBeehiveStatus() {

        System.out.print("Queen laid " + eggsLaid + " eggs!" + 
                         "\nBeehive status\nEgg Count: "+ totalEggsLaid + "\nLarva Count: " + numberOfLarva + "\nPupa Count: " + numberOfPupa +
                         "\nWorker Count: "+ numberOfWorkerBees + "\nDrone Count: " + numberOfDrones + 
                         "\nDeath Count: " + numberOfDeaths + "\nBirth Count: "+ numberOfBirths +
                         "\nHoney Stock: " + honeyStock +"\n");
        printFlowerGarden();
}

workerBee数组的字段索引按照上面指定的顺序排列。每天执行的顺序如下(注意不是完整的)

    addEggToHive(layDailyEggs());
    incrementAge();
    metamorphose();
    printBeehiveStatus();

注意
卵在4天大时孵化成幼虫如果您认为还有其他可能导致问题的原因，请告诉我，我将上传该部分代码。

找到了解决方案。实际上，incrementAge() 方法应该每天将 hive 中所有蜜蜂的年龄增加 1。然而，我只是简单地增加数组中的所有年龄，而不检查该特定行是否是实际的蜜蜂，因为我已将未使用的行初始化为0
