Receive output of python program in java

Question

I've a Python program which just prints "hello world". I only want to get that output in a Java program and print that again, i.e. I want to consume output of Python program in a Java program.

I tried using Runtime.getRuntime().exec("helloworld.py"); but it is giving an exception saying java.lang.IOException : Cannot run program "helloworld.py" : CreateProcess error=193, %1 is not a valid Win32 application.

Can anybody please explain why this exception has occurred and what is solution for it ?

Thanks in advance!

Well it's inside the tin what it says on the outside! A python File can't be a COMPILED WIN32 APPLICATION! — monamona, Feb 28 '18 at 15:40
You should run python and give `"helloworld.py" as a parameter. — Federico klez Culloca, Feb 28 '18 at 15:40
I'm using full path, no issues with that. "You should run python", what exactly does it suggest to do ? I'm sorry, but I'm not familiar with python — Amol.Shaligram, Feb 28 '18 at 15:42
Duplicated post. See https://stackoverflow.com/questions/27267391/running-a-py-file-from-java — Louis Zwawiak, Feb 28 '18 at 15:44
As far as I understand the former comments you may try with something like `.exec("python helloworld.py")`. — U880D, Feb 28 '18 at 15:46

Your file "helloworld.py" isn't a executable file.

Your command allow to run a prompt command.

try : Runtime.getRuntime().exec("python helloworld.py");
