复制代码 代码如下:

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();

}

}

}

如果在eclipse中直接运行报如下错误：

java.io.IOException: Cannot run program "python": CreateProcess error=2

则配置Run Configuration中的Enviroment，增加PATH变量，见下图：
