课程名称：现代Java：数据导向编程大师班 课程概述： 本课程要求学员具备Java（至17版本）的基础知识。我们将深入探讨Java中的数据导向编程（DOP），这是一种现代、实用且具有前瞻性的编程范式，正在重塑Java应用程序的设计与开发方式。在本大师班中，您将学习如何通过将思维方式从对象及继承转向数据与行为的分离，从而编写更清晰、更安全、更易维护的Java代码。通过实践课程和实际案例，您将发现如何利用Java的最新语言特性，如记录、密封类型和模式匹配来构建易于推理和演化的数据驱动应用程序。 您将学到的内容： 1. 现代Java关键特性的快速课程： - 记录（Records）：学习Java记录如何简化数据建模、强制不变性，减少样板代码，及何时选择记录而非类。 - 密封类型（Sealed Types）：掌握密封类和接口，以构建富表达力的、受限的层次结构，消除继承的误用。 - 模式匹配（Pattern Matching）：使用模式匹配和switch表达式简化条件语句，包括嵌套和保护模式。 2. 数据导向编程基础： - 理解DOP的原则及其与传统面向对象编程（OOP）的对比。 - 使用记录和密封类型深入了解代数数据类型（ADTs）在Java中的精准和安全的领域逻辑建模。 3. 实践应用与现实世界集成： - 在实际场景中实现DOP，从API建模到复杂业务规则。 - 使用Jackson序列化和反序列化密封层次结构，包括如何处理JSON中的多态类型。 - 探索数据建模、验证逻辑，以及DOP如何简化状态机和复杂业务工作流。 4. 更好的错误处理： - 使用密封层次结构表示所有可能的错误情况。 - 应用模式匹配以简洁而全面地处理错误，确保没有遗漏边缘案例。 5. 实践期末项目。 为什么选择本课程？ 本课程旨在帮助希望： - 使用现代Java特性的Java开发者提高竞争力。 - 编写更具声明性、可组合性和可读性的代码。 - 用富表达力的数据模型替代遗留样板代码。 - 超越语法理解记录、密封类型和模式匹配的真正价值。 - 学习数据导向思维、ADTs和函数思想而不离开Java。 无论您是构建API、业务系统还是现代后端服务，本课程将改变您在Java中建模、处理和推理数据的方式。
Prerequisite: Prior knowledge of Java (up to version 17)-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.
