本文整理了Java中java.util.Deque.offerFirst()方法的一些代码示例，展示了Deque.offerFirst()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.offerFirst()方法的具体详情如下：
包路径：java.util.Deque
类名称：Deque
方法名：offerFirst

Deque.offerFirst介绍

[英]Inserts the specified element at the front of this deque unless it would violate capacity restrictions. When using a capacity-restricted deque, this method is generally preferable to the #addFirst method, which can fail to insert an element only by throwing an exception.
[中]在此数据块的前面插入指定的元素，除非它违反容量限制。当使用容量受限的deque时，这种方法通常比#addFirst方法更可取，后者只能通过抛出异常来插入元素。
