In this tutorial, learn how to build a ghost writing application in Java using OpenAI's GPT-3 engine. The project requires the Java Development Kit (JDK) version 8 or newer, IntelliJ IDEA Community Edition for convenient and fast Java project development work, and an OpenAI API key. The tutorial guides you through setting up a new Java project in IntelliJ IDEA, adding necessary dependencies, creating a Java class for the ghost writer app, setting the OpenAI API key in IntelliJ IDEA, establishing a connection to the GPT-3 engine, teaching the ghost writer app how to write, and running the ghost writer Java app. The final result is an application that generates spooky stories written for kids just in time for Halloween.
