Java Deque

Показать описание

The Java Deque interface represents a double ended queue (DEQue), meaning a queue which you can enque and deque elements at both ends of the queue. In a normal queue you enque elements at the end, and deque elements from the beginning of the queue. The name Deque is pronounced "deck", like a "deck" of cards.

What do you mean "if the deque is full"? I didn't think they could get full: they can just keep increasing size by 1. Or is it if the deque reaches some memory limit?

christopherrowley

are there no differences between addlast and add??

Java is trash. Why are there so many methods that do the same thing. C++ is much more concise. C++ is superior to java.
