推荐答案

Process p = Runtime.getRuntime().exec("id -u")

请记住，系统上的"root"用户可能不会被称为root(尽管很少更改)，并且也可以将其别名为另一个用户名.如果当前用户是root用户，则输出为0.

Keep in mind that the "root" user on a system may not be called root (although it's rare to change it), and it's also possible to alias it to another username. If the current user is root-like, the output will be 0.
