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

Runtime.halt介绍

[英]Causes the VM to stop running, and the program to exit with the given return code. Use 0 to signal success to the calling process and 1 to signal failure. Neither shutdown hooks nor finalizers are run before exiting. This method is unlikely to be useful to an Android application.
[中]导致VM停止运行，程序以给定的返回代码退出。使用0表示呼叫进程成功，使用1表示失败。退出之前，关闭挂钩和终结器都不会运行。这种方法不太可能对Android应用程序有用。
