java调用python

import java.io.BufferedReader;import java.io.InputStreamReader;import java.io.File;public class test {    public static void main(String[] args) throws Exception {        // TODO Auto-generated method stub        try {            Process p = Runtime.getRuntime().exec("python3 XXX.py");            BufferedReader in = new BufferedReader(new  InputStreamReader(p.getInputStream()));            String line;            while ((line = in.readLine()) != null) {                System.out.println(line);            }            in.close();            p.waitFor();        } catch (Exception e) {            e.printStackTrace();        }    }}

XXX.py为输出字符串
