Converting a jar file to exe file
Use pyinstaller to package the python file in a exe.
Then in the java program replace xyz.py with xyz.exe
Use JarToExe to convert the jar into a Windows .exe file.

This way you would have two exe files but the user would not need to install java or python
Setup

I am running on windows 10
Have python 3.6 and Java 8

description
I have a Java program which calls and passes an argument to a python program and then receives its output using system commands and cmd. 
Question
How do I convert it into a single exe file that is the user can run it without installing java(jdk or jre)  and python. 
Both are a part of my system variable 
Thank you
