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

BitSet.isEmpty介绍

[英]Returns true if all the bits in this BitSet are set to false, false otherwise.
[中]如果此位集中的所有位都设置为false，则返回true，否则返回false。
