Java 队列未正确添加对象

我遇到了一些问题，比如在标题中，在java中将对象添加到队列中。我试图写一些代码来模拟收费亭、汽车和队列。下面是代码

    //Below is creating and naming objects and variables
    int numberOfCars, numberOfTollbooths; 
    double tollboothTotalServiceTime = 0, tollboothAverageServiceTime = 0;
    Scanner keyboard = new Scanner(System.in);
    ExpRandom random = new ExpRandom(13);
    Queue<Car> carQueue = new LinkedList<Car>();

    //Asks the user how many cars need to be created for this simulation
    System.out.print("How many cars do you want to simulate? ");
    numberOfCars = Integer.parseInt(keyboard.next());

    for(int i = 1; i <= numberOfCars; i++)
    {
        carQueue.add(new Car(i, Increasing.increasingNumber()/10));
        System.out.println("Car queue: [" + carQueue.poll() + "]");
    }

当所有的车都加上后，我怎么能看到整个车队？类似于汽车队列：[1,2,3,4…]

对于队列，请使用

peek

System.out.println("Car queue: [" + carQueue.peek() + "]");

问题是什么？我如何查看整个队列？当我添加所有对象时？@user1803052。

System.out.println("Car queue: [" + carQueue.peek() + "]");
