Question

我试图模拟随机数量的客户进入收银台。每个收银机只能容纳10个客户。在每个随机波浪期间，客户最多可以参加5行。

Random rand = new Random(20041995);

for (int j = 0; j < 10; j++)
{
    int pick = rand.nextInt(10);
    System.out.println(pick);
}

这是我正在使用的RNG，并且我正在尝试集成到标准队列结构中，以添加和删除列表中的项目。

这可能会指向正确的方向：

public static void main(String[] args) {

    Random randomCustomer = new Random(); 
    List<Integer> generatedCustomers = new ArrayList<Integer>();

    //counter went up to 50 because each register holds 10 people 
    for(int counter=1; counter<=50;counter++) {
        int customer = randomCustomer.nextInt(20041995);    
        //the random generated customers were then added
        generatedCustomers.add(customer);
    }
        //used the sublist method once i got the size of the array and split it into 5 parts
    for (int start =0; start < generatedCustomers.size(); start += 10) {
        int end = Math.min(start + 10, generatedCustomers.size()); 
        List<Integer> sublist = generatedCustomers.subList(start, end); 
        System.out.println("cash register" + " " + sublist); 
    }
}

}

我的输出产生了这个：
