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

Deque.pop介绍

[英]Pops an element from the stack represented by this deque. In other words, removes and returns the first element of this deque.

This method is equivalent to #removeFirst().
[中]从这个deque表示的堆栈中弹出一个元素。换句话说,删除并返回此数据块的第一个元素。
此方法相当于#removeFirst()。
