Detailed Description
Building a successful career in Java requires understanding that extends from absolute basics to advanced architecture. Without a strong foundation, knowledge gaps emerge that become costly later and hinder your progress in complex projects today here in this track. This is Actlea's most comprehensive foundation course, ensuring a high level of quality across the team through Active Learning. Over five intensive days, we cover the entire language: from syntax and data types to advanced OOP, error handling, and I/O in modern standards. We set up professional project environments and introduce modern functional programming from the start to give you the best possible conditions. You leave the course as a confident developer with a deep understanding of both the language and the ecosystem, ready for the challenges of professional life today.
Recommendation & Next Steps

This is the foundation – continue with 'Modern Functional Java: Streams' later.

Expertise through Active Learning

Java and the Spring Framework have been my core focus for over 20 years. Today, my mission is primarily to help organizations step into the future by integrating intelligent agents and AI-driven features into modern Java systems.

Actlea stands for Active Learning – the philosophy that programming is best learned by writing code, not by watching slides. My workshops focus on intensive, hands-on exercises designed to solve real-world problems.

I deliver proven training concepts globally across all timezones. While I specialize in remote delivery, I love to travel for onsite workshops. My modules are ready for immediate impact but can be tailored to your team's specific requirements.
