Java Reflection: Dynamic Code and Annotations

Unlock the power behind many advanced Java frameworks and libraries by understanding how Java code can examine and modify itself at runtime. This course demystifies reflection, allowing you to build highly adaptable and extensible applications. Upon completion, you will possess the skills to write Java programs that can dynamically interact with their own structure, implement custom metadata solutions, and integrate seamlessly with the Java Module System, elevating your development capabilities. What you'll learn: * Understand the core principles and components of the Java Reflection API. * Apply reflection to dynamically instantiate objects, invoke methods, and access fields. * Create and process custom annotations to add metadata and configuration to your Java code. * Navigate and interact with the Java Module System using reflection effectively. * Explore how reflection integrates with modern Java features such as Records and Sealed Classes. * Implement basic dynamic proxies for intercepting method calls and extending functionality. * Identify and mitigate security considerations when using reflection in applications. This course begins with foundational concepts, systematically guiding you through the practical applications of reflection and annotations, culminating in their use within the Java Module System and modern language features. You will gain a deep understanding through clear explanations and structured code examples. This course is for beginner Java developers who want to understand how to write more dynamic and extensible code, with no prior knowledge of reflection required.
