Objects and Classes vs Data Structures

Objects and Classes vs Data Structures frames the migration decisions Java teams need to make before changing production code. The emphasis is on practical trade-offs: what existing JVM experience still applies, what object-oriented habits should be replaced, and how to review the resulting Clojure design.

Use the child lessons as checkpoints for planning, implementation, and team review rather than as isolated definitions.

• Working with Immutable Data Structures
  Explore the power of immutable data structures in Clojure and learn how to leverage them for robust, scalable applications. This guide provides Java developers with a comprehensive understanding of Clojure's data-centric design, focusing on maps, records, and the benefits of immutability.
• Polymorphism with Protocols and Multimethods
  Explore how Clojure's protocols and multimethods enable polymorphism, offering a flexible alternative to Java's OOP paradigm. Learn to implement protocols for polymorphic behavior and use multimethods for dynamic function dispatch.
