Modern Java Bridge: Refresher

Clean up outdated patterns and upgrade your codebase to modern standards.

Expected Outcome

You get a modern toolbox that eliminates boilerplate and replaces old patterns.

Target Audience

For professional developers wanting to modernize their codebase with Java 17/21.

Prerequisites

Familiarity with Java 8/11 required. For basics, use 'Java Jumpstart: Essentials'.

Curriculum & Highlights

Records for data storage
Switch Expressions
Pattern Matching
Sealed Classes
Modern Stream API
Detailed Description
Many Java applications are locked into patterns from the Java 8 era, resulting in a cumbersome codebase. This technical debt leads to bugs and lowers motivation as teams miss out on modern solutions. Without a focused upgrade, development remains stuck in boilerplate code that hides the actual business logic of your systems today. This workshop addresses these challenges through Active Learning with a focus on pure Java code. I guide you through Java 17 and 21, where we practically refactor code into Records, Switch Expressions and Pattern Matching. By focusing on the language in its purest form, we build a solid foundation for applications that are easier to maintain and develop over time. This approach ensures high quality for your systems today for professional teams here now.

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.
