Java Programming: Inheritance, Overriding, and Core APIs

Writing clean, reusable code in Java requires a solid grasp of object-oriented design and the standard library. If you want to move beyond basic syntax and build structured, real-world applications, understanding how classes interact and how to handle core data types is essential. This text-based course guides you through the core pillars of Java development, focusing on class relationships and essential APIs. You will transition from writing isolated scripts to designing robust, maintainable object-oriented systems using modern Java conventions. What you'll learn: - Understand inheritance and class hierarchies to promote code reuse and structure. - Master method overriding and polymorphism to dynamically change program behavior. - Apply access modifiers like public and private to implement proper data encapsulation. - Configure and use enumerations to represent fixed sets of constants safely. - Practice working with the modern Java Date and Time API for robust temporal calculations. You will start by exploring foundational object-oriented definitions and terminology before diving into practical code structures, access control rules, and standard library utilities. This course is designed for learners who have a basic grasp of Java syntax and want to solidify their understanding of object-oriented principles and core APIs.
