insert_with_priority: add an element to the queue with an associated priority. pull_highest_priority_element: remove the element from the queue that has thehighest priority, and return it. This is also known as "pop_element(Off)", "get_maximum_element" or "get_front(most)_element". Some...

Queue使用时要尽量避免Collection的add()和remove()方法,而是要使用offer()来加入元素,使用poll()来获取并移出元素。 它们的优点是通过返回值可以判断成功与否,add()和remove()方法在失败的时候会抛出异常。 如果要使用前端而不移出该元素,使用element()或者peek()方法。 注意:LinkedList类实现了Queue接口,因此我们可...

标准priority_queue<T>可以通过继承进行自定义。它具有可以在子类中引用的受保护成员c和comp。
PriorityBlockingQueue类能高效处理优先级任务,确保高优先级任务优先执行,它内部基于优先级堆实现,保证了元素的有序性,同时,作为BlockingQueue接口的实现,它提供了线程安全的队列操作,适用于多线程环境下的任务调度与资源管理,简洁而强大的API使得开发者能轻松应对复杂的并发场景。

remove remove方法需要传入一个比较函数,效果是返回并移除符合条件的项,时间复杂度是O(n*log(n)): carsQueue.remove((car)=>car.price===35000);// [{ year: 2013, price: 35000 }]numbersQueue.remove((n)=>n===4);// [4]bidsQueue.remove((bid)=>bid.id===3);// [{ id: 3, value: 10...
