Goodbye Boilerplate: The Visitor Pattern Reimagined in Modern Java | Haim Michael

The Visitor design pattern has been a trusted solution for operating on complex object hierarchies for decades—but its traditional implementation often brings a heavy cost: verbose, repetitive, and hard-to-maintain boilerplate code. In this XtremeJ 2025 session, Haim Michael shows how modern Java finally changes the game. By combining pattern matching, sealed classes, and record classes, Haim demonstrates how the Visitor pattern can become significantly more concise, expressive, and maintainable. Through practical, real-world examples, you’ll see how: ✅ Sealed classes enforce clear and controlled hierarchies ✅ Records simplify data modeling with minimal syntax ✅ Pattern matching makes branching logic cleaner and safer ✅ Boilerplate-heavy structures can be modernized elegantly This talk provides a fresh perspective on a classic design pattern, revealing how Java’s recent language enhancements empower developers to write cleaner, future-ready code without sacrificing structure or clarity. Whether you’re looking to modernize legacy implementations or explore how Java’s evolution improves design patterns, this session will equip you with practical techniques you can apply immediately. ✅ Enjoyed this session?
