Run python from java with an argument

Question

This is my java code. with the script quest.py i want that file.txt to execute from java. but not working. pleaseee help. i am stuck here

String command = "python C:/KDU/genquest-master/quest.py file.txt";
Process p = Runtime.getRuntime().exec(command );

*not working* is not an error description. Can you explain in Detail. BTW Read the error stream to find out what is happening — Jens, Dec 10 '18 at 07:45
I am sure there is an error. You can see it if you read the error stream I guess pyhthon is not in the path or something like that — Jens, Dec 10 '18 at 07:48
Maybe it works on cmd. You run it in the same Directory? with the same user? — Jens, Dec 10 '18 at 07:56
I suggest you use the following code ["Printing Runtime exec() OutputStream to console"](https://stackoverflow.com/questions/3936023/printing-runtime-exec-outputstream-to-console) to print out the output of your python process to the console, this gives an error that you can then use to improve your question — Ferrybig, Dec 10 '18 at 08:00
Have you tried to reat the error strem and took a look if you get any message? — Jens, Dec 10 '18 at 08:03

your problem in python input file.txt you should add complete path of file for python input

String command = "python C:/KDU/genquest-master/quest.py C:/KDU/genquest-master/file.txt";
Process p = Runtime.getRuntime().exec(command );
