JavaLangReflectMethod

JavaLangReflectMethod refers to the Method class within Java's reflection API. This class provides information about a constructor or method of a class. It allows you to dynamically invoke methods on objects, inspect their parameters, and retrieve their return types at runtime.

Using `java.lang.reflect.Method`, you can obtain a `Method` object by calling the `getMethod()` or `getDeclaredMethod()` methods on a `Class` object. `getMethod()` retrieves public methods, including those inherited from superclasses, while `getDeclaredMethod()` retrieves any method declared in the class itself, regardless of its access modifier.

Once you have a `Method` object, you can invoke the method on a specific instance of an object using the `invoke()` method. This method takes the object instance as the first argument, followed by any arguments required by the method being invoked. The return value of the invoked method is returned by `invoke()`. The `Method` class also offers methods to get the method's name, return type, parameter types, modifiers, and exception types. This reflection capability is powerful for creating flexible and dynamic applications, such as frameworks, serialization tools, and dependency injection containers. However, excessive use of reflection can impact performance and reduce code readability and type safety.
