Revisiting Design Patterns after 20

Track: Core Java
In 1994, the Gang of Four brought to us 23 different design patterns that helped thousands, maybe millions of developers, to design better code and share a common language. Almost three decades later, improvements in the Java language allow us to revisit most of these design patterns and propose novel ways to solve the same problems. Join us at this talk when we perform some live refactorings of code using legacy implementations of design patterns into new code using the latest improvements of Java 20. Come and witness how Strategy, Template Method, Visitor, Command, Decorator, Builder, and other patterns can significantly benefit from modern features of Java, such as lambdas, records, switch expressions, and much more.
