Answer
'setAccessible(true)' allows access to private fields.
By default, Java enforces encapsulation, preventing access to private fields. However, using 'setAccessible(true)' on a Field object grants access to modify or retrieve values of private fields. This is particularly useful in frameworks where you might need to map configuration files to private fields in classes. Remember, this can break encapsulation and should be used judiciously to avoid unintended side effects.
