Py4J is an open-source library that allows Python programs running in a Python interpreter to dynamically access Java objects inside a Java Virtual Machine (JVM). Unlike other bridges that load the JVM into the same process space, Py4J communicates using a client-server architecture over network sockets. This means a Java application runs a GatewayServer instance to listen for incoming connections, and a Python application uses a JavaGateway instance to connect to it and invoke methods. Step 1: Install Py4J

First, you need to install the Py4J package in your Python environment. pip install py4j Use code with caution.

You will also need to include the py4j.jar file in your Java project’s classpath. This JAR file is packaged inside the downloaded library or can be fetched from the Official Py4J Website. Step 2: Configure the Java Side (The Server) 3. Advanced Topics – Py4J
