Practical Java Programming with ChatGPT: Develop, Prototype and Validate Java Applications by integrating OpenAI API and leveraging Generative AI and LLMs

If you write Java, you know that even routine coding tasks can consume hours. Practical Java Programming with ChatGPT demonstrates a faster, smarter workflow: describe what you need, let ChatGPT generate the Java code, then implement and validate it in a real development environment. It’s a hands-on guide to integrating OpenAI’s API and large language models into your daily programming.

From Prompts to Working Code 💻

The book walks through actual prompts posed to ChatGPT, mostly via the Android app, and the Java code it returned. You’ll see how to install and use ChatGPT, obtain an OpenAI API key, and make API calls from Java using libraries like OkHttp. Each example is then taken into Eclipse IDE, where the code is set up, run, and tested. The result is a repeatable process for turning natural-language requests into reliable, working Java programs.

What You’ll Explore

• Installing ChatGPT on desktop and Android, plus copyright considerations for AI-generated code.
• Using ChatGPT to discuss and apply SOLID principles in Java.
• Connecting to the OpenAI API from Java with OkHttp.
• Implementing classic algorithms like Binary Search, from generated code to validated output.
• Setting up Eclipse IDE on Windows 10 and Red Hat Enterprise Linux.
• Signal processing tasks: Fourier analysis of audio files and Fast Fourier Transform using Apache Commons Math.
• Document indexing and keyword search with the Lucene library.

Across 13 chapters, the focus stays on practical implementation. You’ll see the exact prompts, the generated code, and the steps needed to make it work.

Who This Book Is For 🧠

Java programmers, software engineers, and solution architects who want to add AI-assisted development to their toolkit. If you have basic IT knowledge and some Java experience, you’ll be able to follow along. The examples target real-world domains like data processing, mathematical analysis, and document management, so the techniques apply to manufacturing, finance, insurance, and other industries.

Why It Matters 💡

Generative AI is changing how software gets written. This book doesn’t just theorize—it shows you how to harness ChatGPT to prototype faster, explore solutions, and reduce boilerplate. The author, Alan S. Bluck, brings over 45 years of software development experience and was named an IBM Champion in 2022 and 2023. His clear, example-driven approach makes advanced AI integration accessible.
