Reflection API
The Reflection API is a programming feature that allows a program to inspect and modify its own structure and behavior at runtime. It enables developers to examine classes, interfaces, fields, methods, and other elements of code dynamically, without knowing their details at compile time. This is commonly used in frameworks, debugging tools, and applications that require runtime analysis or manipulation of objects.
Developers should learn the Reflection API when building tools that need to analyze or modify code dynamically, such as dependency injection frameworks, serialization libraries, or testing frameworks. It is essential for scenarios where you need to inspect class metadata, invoke methods by name, or create objects without compile-time knowledge, making it valuable for flexible and extensible software design.
