如何在2分钟不使用时自动关闭系统？
how to automatically shutdown a system when it is not used for 2 minutes?
如何在不使用时关闭系统。
如果系统有 2 分钟未使用，例如甚至未使用键盘或鼠标或系统中的任何其他应用程序。该系统应该关闭。
如何使这成为可能。
Process class 允许您从下面的 java 运行 windows/any OS 命令是片段
Process proc = runtime.exec("shutdown -s");
System.exit(0);
将上面的代码放在您的逻辑中，您希望如何调用取决于您的逻辑。
Note : Here I am guessing by system you mean your OS. if you mean just
application then just System.exit(0); would suffice.

As asked by OP to check the idle time, I think you need to implement
event listeners mostly mouse and keyboard. Below are some helpful
links to which will help you implement it in your program:
Java mouse motion anywhere on screen
How can I listen for key presses (within Java Swing) across all components?
上述方法是在您通过键盘或鼠标记录事件时设置一个计时器，重置计时器，否则关闭。
