利用 ProcessBuilder.

它可以更轻松地构建过程参数并自动处理命令中的空格问题...

It makes it easier to build the process parameters and takes care of issues with having spaces in commands automatically...

public class TestProcessBuilder {

    public static void main(String[] args) {

        try {
            ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "dir");
            pb.redirectError();
            Process p = pb.start();
            InputStreamConsumer isc = new InputStreamConsumer(p.getInputStream());
            isc.start();
            int exitCode = p.waitFor();

            isc.join();
            System.out.println("Process terminated with " + exitCode);
        } catch (IOException | InterruptedException exp) {
            exp.printStackTrace();
        }

    }

    public static class InputStreamConsumer extends Thread {

        private InputStream is;

        public InputStreamConsumer(InputStream is) {
            this.is = is;
        }

        @Override
        public void run() {

            try {
                int value = -1;
                while ((value = is.read()) != -1) {
                    System.out.print((char)value);
                }
            } catch (IOException exp) {
                exp.printStackTrace();
            }

        }

    }
}

我通常会构建一个通用类，您可以传入命令"(例如dir")及其参数，该类会自动将调用附加到操作系统.如果命令允许输入，我还将包括获取输出的能力，可能通过侦听器回调接口甚至输入...

I'd generally build a all purpose class, which you could pass in the "command" (such as "dir") and it's parameters, that would append the call out to the OS automatically. I would also included the ability to get the output, probably via a listener callback interface and even input, if the command allowed input...
