Description
Lets deep dive into Data Oriented Programming (DOP) in Java. A modern, practical, and forward-looking programming paradigm that is reshaping how Java applications are designed and developed.In this masterclass, you will learn how to write clearer, safer, and more maintainable Java code by shifting your mindset from objects and inheritance to data and behavior separation. Through hands-on lessons and real-world use cases, you will discover how to leverage Java's latest language features Records, Sealed Types, and Pattern Matching to build data-centric applications that are easy to reason about and evolve.What You Will LearnCrash Courses on Key Modern Java FeaturesRecords: Learn how Java Records simplify data modeling, enforce immutability, and reduce boilerplate & when to choose records over classes.Sealed Types: Master sealed classes and interfaces to build expressive, restricted hierarchies and eliminate misuse of inheritance.Pattern Matching: Simplify conditionals using pattern matching with switch expressions, including nested and guarded patterns.Foundations of Data Oriented ProgrammingUnderstand the principles of DOP and how it contrasts with traditional OOP.Dive into Algebraic Data Types (ADTs) in Java using Records and Sealed Types to model domain logic precisely and safely.Practical Use Cases and Real-World IntegrationImplement DOP in real-world scenarios, from API modeling to complex business rules.Serialize and deserialize sealed hierarchies using Jackson including how to work with polymorphic types in JSON.Explore data modeling, validation logic, and how DOP can simplify state machines, complex business workflows.Better Error HandlingUse sealed hierarchies to represent all possible error cases.Apply pattern matching to handle errors in a concise and exhaustive way. No missed edge cases. Hands-On Final ProjectWhy Take This Course?This course is designed for Java developers who want to:Stay ahead with modern Java features Write more declarative, composable, and readable codeReplace legacy boilerplate with expressive data modelsUnderstand the real value of Records, Sealed Types, and Pattern Matching beyond syntaxLearn data oriented thinking, ADTs, and functional ideas without leaving JavaWhether you are building APIs, business systems or modern backend services, this course will transform how you model, process, and reason about data in Java.
