java调用其他语言代码

final Runtime runtime = Runtime.getRuntime();
     Process process = null;
     String[] cmds = {"D:\\APP\\python\\python.exe","E:\\theatre\\src\\test\\java\\com\\devin\\web\\controller\\test.py"};
     try {
         process = new ProcessBuilder(cmds).start();
         BufferedReader stdout = new BufferedReader(new InputStreamReader(process.getInputStream()));
         String l;
         l = stdout.readLine();//读取一行
         System.out.println(l);
     }
     catch(Exception e) {
         System.out.println(e.getMessage());
}
