Deque表示双端队列。双端队列是在两端都可以进行插入和删除的队列。 常用方法: 新建一个双端队列:Deque<Character> deque = new LinkedList<Character>(); 判断是否为空: deque.isEmpty() 增:deque.offerFirst(), deque.offerLast();//从头添加和尾部添加 删:deque.pollFirst(), deque.pollLast()//从头添加...
Deque<Character> stack = new LinkedList<>(); stack.offerLast() stack.pollLast() stack.peekLast() Queue<String> q = new PriorityQueue<>(); Queue<String> q = new PriorityQueue<>((v1, v2) -> v1.val - v2.val); q.poll() q.offer() q.peek()...
Character val = deque.removeLast(); System.out.println("The value that needs to be removed is : "+val); System.out.println("The final deque is : "); for(Character character : deque) { System.out.println(character); } } } Test it Now Output: ADVERTISEMENT The value that needs to b...
