What you'll learn:

• Write modern Java confidently by mastering core fundamentals + OOP, while using AI to accelerate learning and implementation.
• Build real-world Java implementations step-by-step (mini apps + use cases) and learn how to structure code like a professional developer.
• Use AI-assisted development with GitHub Copilot to generate boilerplate, autocomplete code, refactor faster, and stay focused on problem-solving.
• Build real features using Streams, Lambdas, and Functional Interfaces, with Copilot helping you explore patterns and alternatives quickly.
• Learn how to work with AI responsibly: handle knowledge cutoffs, validate outputs, and use prompts that produce reliable, production-ready code.
