Question

我必须在Java中创建一个程序，其中包含从我的队列类创建的队列数组，如下所示 -

class Queue1{  //each line at the supermarket

    public Queue1(int s){                             //constructor
        maxSize = s;
        pplLines = new long[maxSize];
        front = 0;
        rear = -1;
        nItems = 0;
    }

    public void insert(long j){                    //put item at rear of queue
        if(rear == maxSize - 1)                    //deal with wraparound
            rear = -1;
        pplLines[++rear] = j;                      //increment rear and insert
        nItems++;                                  //one more item
    }

    public long remove(){                          //take item from front of queue
        long temp = pplLines[front++];             //get value and increment front
        if(front == maxSize)                       //deal with wraparound
            front = 0;                             
        nItems--;                                  //one less item
        return temp;
    }

    public long peekFront(){                       //peek at front of queue
        return pplLines[front];
    }

    public boolean isEmpty(){                      //true if queue is empty
        return (nItems == 0);
    }

    public boolean isFull(){                       //true if queue is full
        return (nItems == maxSize);
    }

    public int size(){                             //number of items in queue
        return nItems;
    }


    public void display(){                                         //display contents of queue
        for (int i = 0; i < nItems; i++) {
        System.out.println(pplLines[(front + i) % maxSize]);
    }
    }


        }//ends queue class

那么如何将队列类引用到以此

开头的数组中

public SuperMarket（int num_clerks，int line_size）{

之后我创建了一系列队列我需要找到最短的一行来插入一个客户，我必须输入超市里可用的职员/行数，我该如何将其添加到我的SuperMarket类中？

感谢您的帮助！

如果您执行类似

的操作

public SuperMarket(int num_clerks, int line_size){ 

    List<Queue1> clerks = new ArrayList<Queue1>();
    for(int i; i< num_clerks; i++){
        clerks.add(new Queue1(line_size))
    }
}

创建队列数组
