由于之前我们发现出队的时间复杂度不同，我们这里简单测试一下：

package com.company.queue;

import com.sun.javafx.binding.StringFormatter;

import java.util.Random;

/**
 * @program: Array

public class TestQueue {

    public double testQueue(Queue queue, int size) {
        long start = System.nanoTime();
        System.out.println(String.format("%s,开始时间 : %s \n",queue.getClass(), start));
        Random random = new Random();
        for (int i = 0 ; i < size; i++) {
            queue.enqueue(random.nextInt(99999999));
        }
        for (int i = 0 ; i < size; i++) {
            queue.dequeue();
        }

        long end = System.nanoTime();
        System.out.println(String.format("%s,结束时间 : %s \n",queue.getClass(), end));
        System.out.println(String.format("%s, 执行时间: %s \n",queue.getClass(), end - start));
        System.out.println(String.format("----------------------------------------------\n"));
        return (end - start) / 1000000000.0;

    }

    public static void main(String[] args) {
        int size = 100000;
        TestQueue testQueue = new TestQueue();
        double arrayQueueTime = testQueue.testQueue(new ArrayQueue(size), size);
        double loopQueueTime = testQueue.testQueue(new LoopQueue(size), size);
        System.out.println(String.format("arrayQueueTime -  loopQueueTime = %s",
                arrayQueueTime - loopQueueTime));
    }
}

测试结果
