Java GUI可以控制Python后端吗？

Question

Okay so what I have so far is a gui(In Java) and a program(In Python). I want the button in the gui when pressed to send the outputs to the python program and to run it. I then want the gui program to display the python print commands in the text box on the right side.

So, my question is, is this possible and how would I go about making it work?

You can spawn a python process:

Process p = Runtime.getRuntime().exec("python "+yourpythonprog+" "+yourargs);

Then use the Process object to read the output of your python program.
