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

Thread.setPriority介绍

[英]Changes the priority of this thread.

First the checkAccess method of this thread is called with no arguments. This may result in throwing a SecurityException.

Otherwise, the priority of this thread is set to the smaller of the specified newPriority and the maximum permitted priority of the thread's thread group.
[中]更改此线程的优先级。
首先，调用此线程的checkAccess方法时不带任何参数。这可能会导致抛出SecurityException。
否则，此线程的优先级将设置为指定的newPriority和线程线程组的最大允许优先级中的较小者。
