Circular array implementation of Deque Insert Elements at the Front end of Deque: Delete Element From the Front end of Deque resizing array 正确调整数组大小是解决数组队列的难点与重点,非常棘手。需要正确地调整数组大小(即 扩容 和缩容),确保程序在任何给定时间使用的内存量与元素数量成正比。 使用系...
Concurrent Deque Implementations TheLinkedBlockingDequeclass is the concurrent implementation of theDequeinterface. If the deque is empty then methods such astakeFirstandtakeLastwait until the element becomes available, and then retrieves and removes the same element....

Every {@code Queue} implementation must specify its ordering properties. 这里讲了说这个Queue有的是FIFO 有的是LIFO (stack) 一般理解Queue是FIFO, Stack是LIFO The {@link #remove()} and {@link #poll()} methods remove and return the head of the queue. 双端队列其实看方法就可以看出来, 那么...

Specified by: reversed in interface SequencedCollection<E> Implementation Requirements: The implementation in this interface returns a reverse-ordered Deque view. The reversed() method of the view returns a reference to this Deque. Other operations on the view are implemented via calls to public meth...

java.util.LinkedList java.util.ArrayDeque TheLinkedListclass is a pretty standardDequeandQueueimplementation. It uses a linked list internally to model a queue or a deque. The JavaArrayDequeclass stores its elements internally in an array. If the number of elements exceeds the space in the array...
