Java Reflection API

  • The Java Reflection API allows you to inspect and manipulate the metadata of a Java class at runtime.
  • With the Reflection API, you can access class-level information, such as the class name, package, and list of fields and methods, as well as object-level information, such as the values of an object’s fields.

below is an example of using the Reflection API to inspect the metadata of a Car class:

In this example, the metadata of the Car class is accessed using the getClass method of the Car object.

The getDeclaredFields and getDeclaredMethods methods of the Class object are then used to get the fields and methods of the class, respectively.

The value of a field can be accessed using the get method of the Field object, after first setting the field to be accessible using the setAccessible method.
