pip install JPype1

{% include file="examples/python/java.py" %}

See the jpype userguide

I tried this Python 3.7.3 running on Linux.

$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3~19.10-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

$ sudo apt-get install openjdk-8-jdk-headless
$ javac -version
javac 1.8.0_242

{% include file="examples/python/java1/Calculator.java" %} {% include file="examples/python/java1/org/pkg/MyMath.java" %} {% include file="examples/python/java1/calc.py" %}

javac Calculator.java
javac org/pkg/MyMath.java
python calc.py

Directory layout (before running javac):
