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

ArrayDeque.isEmpty介绍

[英]Returns true if this deque contains no elements.
[中]如果此数据不包含任何元素,则返回true。
