本文整理了Java中java.util.Deque.addFirst()方法的一些代码示例，展示了Deque.addFirst()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Deque.addFirst()方法的具体详情如下：
包路径：java.util.Deque
类名称：Deque
方法名：addFirst

Deque.addFirst介绍

[英]Inserts the specified element at the front of this deque if it is possible to do so immediately without violating capacity restrictions. When using a capacity-restricted deque, it is generally preferable to use method #offerFirst.
[中]如果可以在不违反容量限制的情况下立即插入指定的元素，则在该元素的前面插入该元素。使用容量受限设备时，通常最好使用方法#offerFirst。
