java直接调用python脚本的例子

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Main {
 public static void main(String[] args) {
  try {
   System.out.println("start");
   Process pr = Runtime.getRuntime().exec("python test.py");

   BufferedReader in = new BufferedReader(new InputStreamReader(
     pr.getInputStream()));
   String line;
   while ((line = in.readLine()) != null) {
    System.out.println(line);
   }
   in.close();
   pr.waitFor();
   System.out.println("end");
  } catch (Exception e) {
   e.printStackTrace();
  }
 }
}
