Feb 1, 2023 · To invoke an existing Java application in Python, we need a bridge between Python and Java. Packages like Py4j, Pyjnius, Jpype, javabridge, and JCC help invoke Java programs from Python. Also, since Java provides a wide variety of collections, we can directly use them in a Python program by including their java packages in the program.

Pythonis an increasingly popular programming language, particularly in the scientific community due to its rich variety of numerical and statistical packages. Therefore, it’s not an uncommon requirement to be able to invoke Python code from our Java applications. In this tutorial, we’ll take a look at some of the most common ways of calling Python ...
Throughout this tutorial, we’ll use a very simple Python script which we’ll define in a dedicated file called hello.py: Assuming we have a working Python installation when we run our script, we should see the message printed:
In this section, we’ll take a look at two different options we can use to invoke our Python script using core Java.
Continuing with Jython, we also have the possibility of embedding Python code directly into our Java code. We can do this using the PythonInterpretorclass: Using the PythonInterpreter class allows us to execute a string of Python source code via the exec method. As before we use a StringWriterto capture the output from this execution. Now let’s see...
Another third-party library that we could consider using is Apache Common Exec which attempts to overcome some of the shortcomings of the Java Process API. The commons-exec artifact is available from Maven Central: Now let’s how we can use this library: This example is not too dissimilar to our first example using ProcessBuilder. We create a Comman...
Let’s take a step back for a moment and instead of trying to invoke Python directly consider using a well-established protocol like HTTP as an abstraction layer between the two different languages. In actual fact Python ships with a simple built-in HTTP server which we can use for sharing content or files over HTTP: If we now go to http://localhost...
In this tutorial, we’ve learned about some of the most popular technologies for calling Python code from Java. As always, the full source code of the article is available over on GitHub.
