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

Deque.element介绍

[英]Retrieves, but does not remove, the head of the queue represented by this deque (in other words, the first element of this deque). This method differs from #peek only in that it throws an exception if this deque is empty.

This method is equivalent to #getFirst().
[中]检索但不删除此deque表示的队列头（换句话说，此deque的第一个元素）。此方法与#peek的不同之处在于，如果此deque为空，则会引发异常。
此方法相当于#getFirst（）。
