Java 调用系统系统可执行文件

public class Test {

    public static Map<String, String> executeCmd(String cmd) {
        Runtime rt = Runtime.getRuntime(); // 运行时系统获取
        Map<String, String> lineMap = new HashMap<String, String>();//存放返回值
        try {
            Process proc = rt.exec(cmd);// 执行命令
            InputStream stderr = proc.getInputStream();//执行结果 得到进程的标准输出信息流
            InputStreamReader isr = new InputStreamReader(stderr);//将字节流转化成字符流
            BufferedReader br = new BufferedReader(isr);//将字符流以缓存的形式一行一行输出
            String line = null;
            while ((line = br.readLine()) != null) {
                if (!StringUtils.isEmpty(line)) {
                    String[] strLine = line.split(":");
                    if(strLine.length>=2) {
                        lineMap.put(strLine[0].trim(), strLine[1].trim());
                    }

                }
            }
            br.close();
            isr.close();
            stderr.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return lineMap;
    }

    public static void main(String []args){
            executeCmd("mstsc");
    }
