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

Thread.isDaemon介绍

[英]Tests if this thread is a daemon thread.
[中]测试此线程是否为守护进程线程。
