Java + AI: Why Every Java Developer Should Learn AI-Powered Coding in 2025

Why write 100 lines of boilerplate code when AI can do it in seconds?

“Why write 100 lines of boilerplate code when AI can do it in seconds?”

If that question made you raise your eyebrows, keep reading, because the future of Java development isn’t just about writing better code.

It’s about writing code smarter, faster, with the help of AI-powered tools like GitHub Copilot.

Whether you’re still learning Java or have years of experience under your belt, this shift affects you directly as its affecting me, a Java developer with more than 20 years of experience.

When I am seeing the AI Agent mode of GitHub copilot implementing the whole feature in few minutes in front of me, its nothing short of magic. To be honest I have never imagined anyone can write code so fast.

While GitHub CoPilot was great but its agentic mode which is available for VS code and IntelliJIDEA takes the AI coding or Vibe coding game one level up.

GitHub Copilot is your coding buddy you always look for, and its only going to help, so it makes a lot of sense that you increase your friendship with GitHub copilot and start learning them.

If you’re new to Copilot, I’d recommend this free course : GitHub Copilot for Java Developers.

The Java Landscape Has Changed!

Let’s face it! Java has always had a reputation of being verbose, enterprise-heavy, and sometimes slow to write compared to “newer” languages.

But the fact is, Java isn’t going anywhere. In fact, with Spring Boot, microservices, and Android, it’s stronger than ever in enterprise application development.

What really changed is how we write Java.

With tools like Copilot, developers are moving away from writing repetitive code to AI-assisted development, where the IDE understands exactly what you’re trying to do, and writes most of it for you!

So What Exactly Is AI-Powered Coding?

Think of it like autocomplete on steroids. GitHub Copilot, trained on billions of lines of source code, can:

  • Write entire methods based on your function name
  • Generate unit tests from your Java code
  • Write boilerplate classes for you (Like DTOs, models, controllers, you name it!)
  • Assists you in fixing bugs and suggest cleaner ways to write code

And it all happens in real time, as you type, and if you have seen the AI agentic mode for GitHub copilot, you will know that it can write code, test, and even trigger build and run the program for you.

The MCP has really changed the game and more and more tool is offering more automation and capabilities by integrating various essential tools via MCP.

For example, VS code now support MCP and Agent Mode for Vibe coding.

Why You Can’t Afford to Ignore It ?

Still coding like it’s 2015? Here’s what you risk:

  • Falling behind your peers who are 2x–3x more productive
  • Spending hours debugging problems that Copilot can hint at in seconds
  • Missing out on interviews where AI literacy is becoming a sought-after skill
  • Wasting time writing the same code over and over

The developers who are getting ahead in 2025, aren’t just the ones writing the best code.

They’re the ones who are writing it faster, with the help of AI.

And, as AI adoption increasing exponentially, it become essential for any developer to get familiar with AI tools like GitHub Copilot, cursor, ChatGPT etc, especially GitHub Copilot because Microsoft is backing it and I have seen more and more companies are using it.

Here is also a nice GitHub Copilot cheat sheet you can refer for quick overview of essential commands:

Here’s the Twist: AI Helps You Learn, Not Just Code

If you’re worried Copilot might make you lazy, you need to think again.

As a Java pro, I’ve seen firsthand how beginner coders actually learn faster by seeing Copilot’s suggestions in real-time.

Every time Copilot makes a suggestion, they’d ask themselves:

“Oh, so that’s how a for-each loop works with a Stream!”
“Wait, why did it use a Map<String, List<Integer>> here?”

Every suggestion brings curiosity and becomes a learning moment, and you can even ask Copilot why it suggested what it did.

And if you’re a Java Developer, this free course from Karpado will help: GitHub Copilot for Java Developers.

The Bottom Line

AI isn’t going to replace Java developers.

But Java developers who use AI will absolutely outpace those who don’t.

This isn’t about coding shortcuts. It’s about working smarter, learning faster, and preparing for the future of software development.

More and more companies are introducing AI tools especially GitHub copilot in their development environment and its high time that you learn GitHub Copilot not just to improve your productivity and shine but also to stay ahead from your competition.

If you want to do just one thing? download VS Code and start exploring how to code Java on Agent mode. Create a project and you will be surprised what you can do in few minutes.

P. S. — Btw, if you are in rush and just want to start learning, you can go ahead and start with this Become Full Stack Developer course on Karpado, one of the best place to learn Java and fullstack development for Java developer. They are also offering big discount at the moment.
