Modern Java: Data Oriented Programming Masterclass

Dive into Data Oriented Programming (DOP) in Java and unlock a modern approach to application development! This masterclass is designed for Java developers with prior experience (up to Java 17) who want to write clearer, safer, and more maintainable code. We'll shift your focus from traditional object-oriented programming (OOP) and inheritance to data and behavior separation, building data-centric applications that are easier to understand and evolve.

What You Will Learn:

• Modern Java Features Crash Course: Get up to speed with the latest Java advancements.
• Java Records: Discover how to simplify data modeling, enforce immutability, and reduce boilerplate code. Learn when to effectively use Records versus traditional classes.
• Sealed Types: Master sealed classes and interfaces to create expressive, restricted hierarchies and prevent misuse of inheritance.
• Pattern Matching: Simplify complex conditionals using pattern matching with switch expressions, including nested and guarded patterns for more concise code.

Foundations of Data Oriented Programming (DOP):

• Understand the core principles of DOP and how it differs from traditional OOP.
• Explore Algebraic Data Types (ADTs) in Java, leveraging Records and Sealed Types for precise and safe domain logic modeling.

Practical Use Cases & Real-World Integration:

• Implement DOP in practical scenarios, from API modeling to complex business rules.
• Serialize and deserialize sealed hierarchies using Jackson, including handling polymorphic types in JSON.
• Explore data modeling, validation logic, and how DOP can streamline state machines and complex business workflows.

Enhanced Error Handling:

• Use sealed hierarchies to represent all possible error cases.
• Apply pattern matching for concise and exhaustive error handling, ensuring no edge cases are missed.

Hands-On Final Project: Apply your newly acquired knowledge to a real-world project.

Why Take This Course?

This course is ideal for Java developers who:

• Want to stay ahead with modern Java features.
• Aim to write more declarative, composable, and readable code.
• Want to replace legacy boilerplate with expressive data models.
• Understand the true value of Records, Sealed Types, and Pattern Matching beyond syntax.
• Want to learn data-oriented thinking, ADTs, and functional concepts within the Java ecosystem.

Whether you're building APIs, business systems, or modern backend services, this course will transform how you model, process, and reason about data in Java.
