Java Reflection API: How to Use Java Reflection to Inspect Methods

Показать описание
Method reflection in Java allows programs to analyze and manipulate objects at runtime. This technique is pivotal for scenarios requiring dynamic behavior, such as serialization, deserialization, and frameworks that instantiate objects and call methods without knowing the class types beforehand. Using reflection, developers can inspect object methods, invoke them, and alter their accessibility, facilitating flexible and dynamic code execution.

This code example demonstrates basic usage of method reflection by inspecting methods of the ArrayList class. It retrieves the Class object for ArrayList, obtains all declared methods, and prints each method's name, return type, and parameter types, showcasing reflection's ability to introspect class information at runtime.
