What are the commonly used classes in Java reflection?

The commonly used classes in Java reflection mechanism are as follows:

1. Class class: Represents the class being reflected, allowing access to its properties, methods, constructors, and other information.

2. Field Class: Represents the member variables of a class, allowing for the retrieval and setting of variable values.

Method class: represents the methods of a class, allowing to invoke methods and retrieve their return values.

The Constructor class represents the class’s constructor, which can create instances of the class.

5. Modifier class: this class can access and adjust the modifiers of classes, member variables, methods, and constructors.

6. Array class: Used for manipulating arrays, it can create, retrieve, and set array values.

7. Proxy class: used to create dynamic proxy objects that can generate proxy classes at runtime.

In addition to the commonly used classes mentioned above, there are several other classes that are also frequently used, such as AnnotatedElement class, Parameter class, etc. These classes can be used to retrieve annotation information, method parameter information, etc.
