我正在尝试运行外部可执行文件,但显然它需要提升.代码是这样的,从使用ProcessBuilder的示例修改(因此具有一个参数的数组):

    public static void main(String[] args) throws IOException {
        File demo = new File("C:\\xyzwsdemo");
        if(!demo.exists()) demo.mkdirs();
        String[] command = {"C:\\fakepath\\bsdiff4.3-win32\\bspatch.exe"};
        ProcessBuilder pb = new ProcessBuilder( command );
        Process process = pb.start();
        InputStream is = process.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line;
        System.out.printf("Output of running %s is:\n", Arrays.toString(command));
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
        try {
            int exitValue = process.waitFor();
            System.out.println("\n\nExit Value is " + exitValue);
        } catch (InterruptedException e) {
            e.printStackTrace(); …
