推荐答案

您需要在要执行此操作的计算机中安装python解释器，然后将该解释器作为Java的外部命令来调用.

You need to have the python interpreter installed in the machine where you want to do that and call this interpreter as an external command from Java.

从那里:

String[] params = new String [2];
params[0] = PATH2_YOUR_PYTHON_SETUP + "python.exe";
params[1] = PATH2_YOUR_PYTHON_SCRIPT;
Runtime.getRuntime().exec(params);

此外，您可以使用返回的 Process exec中的对象与您的脚本输入/输出进行交互.

Additionally, you can use the returned Process object from exec to interact with your script input/output.
