LinkedList 类实现了 Queue 接口,因此可以直接用作队列: importjava.util.LinkedList;importjava.util.Queue;publicclassQueueExample{publicstaticvoidmain(String[] args){ Queue<String> queue =newLinkedList<>();// 入队queue.offer("Apple"); queue.offer("Banana"); queue.offer("Cherry"); System.out.prin...
Java example to take elements from PriorityBlockingQueue using blocking retrieval. A thread will wait until there is an element present in the queue. In given example, a thread is waiting on queue in infinite loop usingtake()method. It wait for 1 seconds before checking again. As soon as w...
1.4Java BlockingQueue Example – Service Java BlockingQueue Java BlockingQueue doesn’t acceptnullvalues and throwNullPointerExceptionif you try to store null value in the queue. Java BlockingQueue implementations arethread-safe. All queuing methods are atomic in nature and use internal locks or othe...
util.*; public class QueueDequeExample { public static void main(String[] args) { Deque<Integer> deque = new ArrayDeque<>(); Queue<Integer> queue = new LinkedList<>(); deque.addFirst(1); // 添加到头部 deque.addLast(2); // 添加到尾部 queue.offer(3); // 添加到Queue尾部 System.out...
代码示例下面是一个简单的 Queue 接口使用示例，使用了 LinkedList 类作为实现，如下代码：import java.util.LinkedList; import java.util.Queue; publicclassQueueExample{ publicstaticvoidmain(String[] args){ Queue<String> queue = new LinkedList<>(); // 插入元素 queue.offer("Apple"); ...
LinkedList类是Java中的一个双向链表类,它实现了List和Deque接口,也可以用来实现队列。我们可以使用LinkedList来创建一个FIFO(先进先出)队列。 以下是使用LinkedList实现队列的示例代码: importjava.util.LinkedList;importjava.util.Queue;publicclassQueueExample{publicstaticvoidmain(String[]args){Queue<String>queue=new...
import java.util.LinkedList; public class DequeExample { public static void main(String[] args) { Deque<String> deque = new LinkedList<>(); // 在队列头部添加元素 deque.addFirst("Element 1 (Head)"); // 在队列尾部添加元素 deque.addLast("Element 2 (Tail)"); ...
//starting producer to produce messages in queue new Thread(producer).start(); //starting consumer to consume messages from queue new Thread(consumer).start(); System.out.println("Producer and Consumer has been started"); } } Output of the above java BlockingQueue example program is shown be...
