Go Beyond Core Java: A Deep Dive into the JVM and API Design
What you'll learn
Re-implement Spring's core dependency injection from scratch, manually managing the bean lifecycle from classpath scanning to instantiation
Gain a deeper understanding of the JVM by reading the bytecode generated from your own Java code
Design flexible and reusable APIs by applying the PECS principle (Producer Extends, Consumer Super) to generic method signatures
Build fluent, chainable APIs by implementing the self-referential generics pattern to ensure methods return the correct subtype
Design type-safe generic components by using multiple bounds to guarantee a type supports behaviors from different classes and interfaces
Explain how type erasure creates fundamental limitations in Java generics
Build dynamic and extensible applications by using the Reflection API to inspect classes, invoke methods, and manipulate fields at runtime
Use dynamic proxies and an InvocationHandler to inject concerns (e.g., logging) into business logic without modifying the original class
Requirements
This course requires a solid foundation in core Java, including practical experience with object-oriented programming, the Collections Framework, and basic generics
Practical Java Development Experience: You should be able to write, compile, and run Java applications using a modern IDE like IntelliJ IDEA, Eclipse, or VS Code
Description
Are you an intermediate Java developer who uses powerful frameworks like Spring, Hibernate, or Mockito, but doesn't fully understand the "magic" that makes them work?Have you ever wondered how @Autowired injects a dependency or how @Transactional manages a database session?If you're ready to move beyond just using frameworks and want to master the deep, powerful mechanics of the Java platform itself, then this course is your next step. This is not just another "Core Java" course. This is a deep dive into the advanced, "under-the-hood" concepts that separate senior developers from the crowd. By the end of this course, you will be able to:Master Advanced Generics: Go beyond List and conquer complex topics like PECS (? extends T vs. ? super T), self-referential patterns for fluent APIs, and the subtle but critical implications of type erasure.Harness the Power of the Reflection API: Learn to inspect classes, invoke methods, and manipulate fields at runtime to build truly dynamic and flexible applications.Create Dynamic Proxies: Understand the core mechanism behind AOP (Aspect-Oriented Programming) by creating proxies that can intercept method calls to add logging, security, or caching-without touching the original code.Build Your Own Spring IoC Container: Demystify @Autowired by re-implementing Spring's core dependency injection mechanism from scratch. You'll manage the entire bean lifecycle, from classpath scanning and bean definition to final instantiation and injection.Dissect Java Bytecode: Use the Java Class File Disassembler (javap) to see what the compiler is really doing with your code, giving you a profound understanding of the JVM.This course is a direct, hands-on journey into the heart of the Java platform. You won't just learn theory; you will build practical examples that demystify these advanced topics and give you the confidence to use them in your own projects.If you are ready to stop being a magician's audience and start becoming the magician, this course is for you.Enroll today and take the next major step in your journey to becoming a senior Java expert!
Who this course is for
This course is for intermediate to advanced Java developers who are ready to master the powerful, "under-the-hood" mechanics of the language. It is perfect for curious developers who want to understand how frameworks like Spring and Hibernate work, rather than just using them. You will gain the deep knowledge needed to design your own flexible APIs and prepare for senior-level technical interviews. The course teaches you to solve complex problems using advanced topics like reflection, dynamic proxies, and dependency injection. If you want to transition from simply writing application code to truly understanding the Java platform, this course is for you
