以下是要走的路：

Runtime rt = Runtime.getRuntime();
String[] commands = {"system.exe","-get t"};
Process proc = rt.exec(commands);

BufferedReader stdInput = new BufferedReader(new 
     InputStreamReader(proc.getInputStream()));

BufferedReader stdError = new BufferedReader(new 
     InputStreamReader(proc.getErrorStream()));

// read the output from the command
System.out.println("Here is the standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null) {
    System.out.println(s);
}

// read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
    System.out.println(s);
}

更好地阅读Javadoc了解更多详情这里。 ProcessBuilder 将是不错的选择

Better read the Javadoc for more details here. ProcessBuilder would be good choice to use
