如何在java中运行sudo poweroff

import java.io.IOException;

public class ShutdownExample {
    public static void main(String[] args) {
        try {
            ProcessBuilder processBuilder = new ProcessBuilder("sudo", "poweroff");
            Process process = processBuilder.start();
            int exitCode = process.waitFor();
            if (exitCode == 0) {
                System.out.println("操作系统已关闭");
            } else {
                System.out.println("操作系统关闭失败");
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
